Make a pledge and measure your actions with entries in an RSS feed. RSS feeds can track lots of things, like posts or Youtube videos or GitHub releases! If you don't make progress, Beeminder will take your money.

Post the video, release the software, write the blog...
Each new entry in the feed will count as progress towards your goal.

Beeminder will warn you if you're in the danger zone. As long as your dots don't cross the bright red line, your money is safe! (Details on our blog.)
