I actually created a logarithmic calendar app for a class a few years ago... Maybe I'll dig it out, update it and post since other people seem to like the idea...
Pay for my time and I will. Don't post a comment with "Just do it..." when you have no idea what other stuff I have going on or how much effort it would be to get it to any sort of presentable state.
One 'getting things done' tip I've adopted is to catch myself writing "I will" in an email and change it to "I have", then go and do it. It works pretty well.
I think saying 'Maybe I'll...' is a perfectly good way to poll if there's enough interest to make the effort worthwhile.
Getting upvotes and supportive comments like "Please do, I'd like to see that" would make the follow-through posting more likely. Critical complaints like yours make the follow-through posting less likely.
