A bot that takes all your unfinished bot ideas and randomly selects one of them for you to work on, and tweets you. Maybe it looks at the people you follow (or the people that follow you) on Twitter, and says "Hey, @[random follower of you], the next time you see @[your twitter account], remind [gender] that to work on [project XYZ]!" to give some social oomph to it. Those followers would have to opt-in, but could only be people that you know.
You'd have to have a machine-readable list of unfinished projects, maybe some of them have URLs like a GitHub repository.
