You may not need it anymore but my startup is trying to get people to where you've gotten. In the case of NaNoWriMo, the idea is to force yourself to spread out the writing over the whole month: http://blog.beeminder.com/nanowrimo
I happened to have looked into your service in regards to tracking word count, but had some trouble figuring it out and making it fit into my workflow.
I'll check it out again, though, as I want to get back into exercising this month. Thanks for the reminder!
