In spite of Twitter’s ten-fold growth in 2008, a lot of perfectly well-adjusted and otherwise hip people (including myself) have yet to integrate the service into their life in a significant way. If you’re not familiar with what Twitter actually is, the TED presentation by Twitter co-founder Evan Williams featured here here will give you a good overview. Even if you are familiar with Twitter, you may not be aware of Twitter’s effect on ancient history, or more recently, Hitler. And even more recently (and more seriously) you might not be aware of some of the the amazing tools at your disposal, like Twitterfall, where you can mindlessly watch tweets scroll by, or better yet, intelligently customize what you see. Or Tweetoclock, which lets you type in a Twitter username to find out when it’s best to tweet them. And if you’re using Twitter aggressively for marketing purposes, you’ll need Tweetsum, which uses sophisticated algorithms to generate a DBI (Douche Bag Index) to help you manage followers. My personal prediction (but I never saw Reality TV lasting this long, so ignore me!) is that Twitter, as it’s currently used, will become quite popular, but have a short life cycle. Or, as Evan Williams suggests, do something completely unexpected because users find a new use for it. And you can Twote me on that, to use some twerminology I just Twopyrighted. And regarding the buzz going around that Twitter has no viable business model? One of their key venture capitalists is just laughing.
