Ahhhh, The Onion. Yep. This sort of speaks for itself.

A little light evening reading…

Careful analysis of Figure 1, filtered through intense algorithms and exhaustive research, has determined to high precision that the Universe is freaking awesome. The uncertainty band on this conclusion was considered too narrow for quantification; the margin of error is effectively zero.

Why I Use Twitter and Not Facebook

I have officially now been asked this question enough that I think it deserves a blog post: “Why do I avoid Facebook and yet use Twitter all the time?” There is an expectation for many that if Facebook is superficial, then Twitter must be even more so. And then I find myself in really long convoluted explanations because I’ve never sat down and sorted it out logically.

So here goes, my reasons why Twitter » Facebook.

  1. Non-reciprocity. On Facebook, you can’t accept a friend request without friending them back. That is, Facebook is a two-way information flow, and attempts to form a relationship between the two people under the presumption that both people actually care about what the other is saying or doing. Twitter makes no such presumption.

    Don’t like the “I’m so high right now lolz” type of tweets? Or the ones that may be erudite and well put-together, but just aren’t relevant to you? Just don’t follow them. Unlike Facebook, there is zero expectation on Twitter that you follow anyone in particular, including people you know or people who follow you. On Facebook this would be rude, since you would have to mute or unfriend someone, and there is all this social diplomacy tied up in friending that leads to a lot of b.s.

    In other words, Twitter acknowledges the difference between 1) people with whom you want to maintain social/diplomatic contact and 2) people who actually post things that interest you or that you want to engage with. There is generally a fair bit of overlap between the two groups of people, but they are not the same thing.

  2. Information and ideas, not people. I would guess that about 80% of the people I follow on Twitter I have never met in my life and probably never will. A significant number are actually not people, but institutions, such as news organizations, educational institutions, nonprofits, or advocacy groups. This is because they post information and observations about things that I actually find interesting or useful. For example: NPR, NASA, various NASA missions, the Smithsonian, Rachael Maddow, Scientific American, Boston Public Schools, BadAstronomer, Neil deGrasse Tyson, Radiolab, Slashdot, the Dalai Lama, etc. The full power of Twitter’s unbelievable information delivery capability gets even better if you make parallel feeds using Lists and standing searches, via a third-party client like TweetDeck. Look for those putting out good tweets. A good tweet stands on its own as insightful, informational, or funny, or it contains a link to something that is, or is about something you directly relate to.

    This ties back to non-reciprocity: I actually know many people who have a Twitter account just to get updates on everything they are interested in, and never actually tweet themselves. This is totally legit on Twitter and actually gets to the core of what Twitter is about, whereas on Facebook this would basically be stalking, because Facebook is more about people than information.

  3. Hashtags. By clicking on a #hashtag, I can pull up all tweets on the subject that are being posted anywhere in the world, by anyone, right now, regardless of whether I know them or not, and without any obligation to make any other connection with them. On Facebook, I would have to search for the person/organization and friend/Like them before seeing the content. Hashtags connect people and ideas that would never cross in real life or on Facebook.
  4. Simplicity. Facebook has evolved a long way from when it first came out during my college years. It is now full of an astounding array of mind-bogglingly inane features. Whereas Facebook seems to add a new creeptastic or needlessly complex feature every few months, Twitter has remained fairly straightforwardly simple and focused on what has always been its core: content.

    There are no profiles. Twitter gives you 1 photo and 160 characters in which to describe yourself. There are no Likes, no long self-absorbed narratives, no photos that aren’t relevant to the present moment/conversation, no boxes to describe everything you do and stand for, no apps to my waste time and leech my personal information, no blanket invites to events in cities I no longer live in, etc, etc. Twitter is not about you, but your content. (Unless you are a pop culture celebrity or sports star, which most people are not.)

So, a lot of this is more due to the the culture of the two social media, especially after a lot of changes that Facebook made in response to Twitter and G+. Yes, I could use Facebook Pages to control one-way information flow and follow ideas and institutions I like. I could sort friends into groups and attempt to control who sees what information. I could mute the people I “have” to stay friends with but who post inane crap, so that their content doesn’t show up on my news feed. I could block apps and invites, take down my personal information, focus only on posting “meaningful” things, and be among that oft-mocked group of digital curmudgeons that use Facebook to complain about Facebook. But in the end… why?

Regardless of whether using Facebook as I would want to use it is possible, the whole culture of the site is structured to emphasize what I don’t like about it and drown out what I do like about it. So especially when there is a social medium for what I do like, that has a sizeable portion of the userbase using it like I do, why not use that one instead?

Things I do use Facebook for:

  • Establishing/maintaining contact with people that I either just met, don’t see very often, or haven’t seen in a long time. It’s great for looking up where people are now, what their current email address or phone number is, and messaging them to get in or get back in touch. That is, Facebook is a great dossier of contacts.
  • Engaging with organizations in which I am a member which use Facebook as their primary means of accomplishing this. For example, the closed/private Facebook group for my residency program’s cohort is the only thing on Facebook right now that sends me notifications. Back when I was running a theatre company, I used Facebook a lot to engage with our fans. Etc.
  • Broadcasting causes or information that I believe a very wide array of people would be interested in knowing or knowing about, and/or that I would like to broadcast to a very wide array of people in a certain area. This is extraordinarily rare. For example, posting what furniture I had for sale from downsizing my house. This could be of interest to many people, regardless of their political or social alignments, and is focused on people living in my geographic area. Twitter does not allow any selection of who receives the message, so Facebook is better at this kind of thing.

I remember a friend saying once “Facebook is great for finding people who were once friends but now mostly aren’t; Twitter is great for finding people who aren’t friends now but we probably would be if we ever met.”

And that’s the thing really.

Why we should use the Oxford Comma







A direct quote from The Times newspaper, talking about a Peter Ustinov documentary and saying that:

 “highlights of his global tour include encounters with Nelson Mandela, an 800-year-old demigod and a dildo collector”.

Forever reblog.

okay fine i’ll start using the oxford comma

i’m convinced




Any questions?

Nakkula, M.J., & Toshalis, E. (2006).  Understanding youth.  Adolescent development for educators.  Cambridge, MA:  Harvard Education Press.  Chapter 7 (Racial identity development)

Scientifically, there is no such thing as “race.” As many biologists and geneticists have pointed out, including the late Stephen Jay Gould [2], there exists as much genetic diversity within any racial group as there is within the human population as a whole. There is no biologically sustainable reason for establishing “races” as distinct subgroups within the human species, which is why Omi and Winant call racial categories “patently absurd reductions of human variation.” [3] That there are unique bodily features (skin color, hair texture, shape of eyes, etc) distributed according to regional ancestral origin supports nothing “racial” except for an appreciation for the ways our species adapted to specific environments over hundreds of thousands of years.

Culturally, socio-politically, economically, yes. Biologically, no. NO. In other words, we choose to do this to ourselves, which means of course that we can choose differently within our own spheres of influence.

The cloud bands of Jupiter stripe the planet with turbulence. Throughout its upper atmosphere, Jupiter shows signs of gravity waves and complicated wave patterns. Near the equator, the cloud bands are driven by planetary winds that reach speeds of 500 kph, whereas near the poles, the clouds show greater evidence of mottling and convection. At present, the reasons for this patterning are undetermined. (Image Credit: NASA; via APOD)
