A personal version of Basecamp, the well loved project management system for businesses, is out now for $25. Project management software sounds boring and staid and zzzzzzz and that's probably about right, but it's also crucial to, like, getting anything done, so this is nice for anyone who's got personal side projects they want to keep tabs on.
The $25 is a one-time fee, and a lot cheaper than the business version, but you'll have to re-up for another $25 if you want to start a second project using the personal version. For now, it's only available to current Basecamp users, but 37signals' site implies that'll change after a few months. [37signals]
