With Twitter’s ever growing reach and limitless possibilities, I thought it’d be handy for the world to have a simple little list of all the robots, services, and otherwise non-human twitter users. A few minutes ago I finished just that: the Twitter Service Directory.
To keep updated on the latest submissions, you can follow @ServiceBook, which gets updated after every accepted submission.
Be gentle with it for now. I have it using ServiceBook’s API calls whenever a new username is submitted, and if a call fails it doesn’t tell you. I’ll rewrite it later to only suck up those API calls when I use my mod powers (hooray wordpress plugins!), or if its close to the end of an hour where calls reset back to 30.
