I'd love to convince you to beemind projects that you want to force yourself to see to fruition. http://beeminder.com (I'm a co-founder)
If I'm lucky others will chime in to back me up that it's astoundingly effective for exactly the psychology you describe. We can unambiguously say that Beeminder itself wouldn't have survived without beeminding it. :)
Looks like an interesting project; suggestion: reshoot your intro video without making Bethany laugh while she's explaining how the site works - I found it very distracting and thus hard to take her seriously. If she's just a giggler by nature then maybe find someone else to do the presentation :-)
Ha, I think you're right, and thanks for that feedback! We just hate doing videos and a/b tests say that that beats the pants off the alternative of a nice, professional static image. So we're going with what we got for now.
And, yes, that's me making her laugh. I was trying hard to get her to conceal how much she hates making videos! :)
But let's save this stuff for our next "Show HN". For this thread I'm really eager to hear thoughts on whether self-tracking and commitment devices are a good approach to the OP's problem.
