News is making the rounds that Twitter has put up a directory showing all the open source projects it loves, which in real terms means the projects that Twitter contributes to. It's an impressive list of projects, including cachet, its Java-based text-processing software for handling Tweets, contributions to several Ruby tools, and other major contributions. Of course, notably absent is the actual platform that runs Twitter itself ? so the love only runs so deep, apparently.
I don't mean to pick on Twitter too much, but if the company is going to declare its love for open source, why not go all the way? Or at least mention the elephant in the room: The primary platform is still closed. Other companies, however, really do go all out in showing their love for open source. You can get a similar microblogging platform from the all-open Status.net, which runs the Identi.ca microblogging service.
