Since most of my posts lately have been tweets rather than actual writings, and also since I’ve gotten several requests lately for definitions of what twitter is from friends of mine who don’t use it …
First I present two things twitter isn’t.

couldn't tell you the source for this one
As usual, Wikipedia summarizes the microblogging site quite well, but it’s missing … something. I’m not sure what, exactly, but there are nuances about Twitter (oh, God, have I gone hipster?) that aren’t touched on.
The easiest way to describe it for those familiar with Facebook is to just say that it’s just like the status updates, without all the annoying apps and quizzes that get in the way. That’s not to say I don’t like Facebook apps; I have sent more than my share of Pieces of Flair, and play at least a couple turns of Scrabble a day. When it gets down to it, however, Facebook (for me) is about status updates.
Twitter asks its users to answer a very simple question, at any given time: “What are you doing?” Since I started using Twitter almost 2 years ago, I have mostly forgotten the question and just send out random thoughts that run through my head. Not many of them are insightful, witty, or clever, but I’d say the proportion of insightful, witty, and clever tweets to insightful, witty, and clever thoughts is pretty close to 1:1. Maybe the question has been cerebrally translated to “What are you thinking?”, as most of the time I’m not actually doing anything (see video above).
Anyway, it’s turned into a crutch for me of sorts. I don’t write longer entries with actual content anymore, because twitter has let me rest on 140 characters of pure laziness (though occasionally I have to chop a couple words out to make it fit, which can take some thought). It’s blogging for the ADD-afflicted. Maybe I ought to set a goal to write an expand-on-this-tweet entry at least once a day. And I’d be willing to accept nominations, either via comments here or on Facebook (as I’ve set my Twitter app to update my status on Facebook).
Oh, and if all this hasn’t convinced you to join Twitter (or has scared you away from it completely), you might be interested in this factoid: Twitterer’s tweets are available via RSS feed. If you don’t want to sign up for an account yourself, but you do want to “follow” me or the tweets of your favorite Celebritwitterer, just click on the link on the right hand side of their Twitter page, or at the end of your address bar if you’re using Firefox (maybe other browsers, too, but I wouldn’t know about that).
