What people don't know or forget: You can always start minimally. For personal projects, it turns out a text file works for 99% of use cases. Text editor, vi or emacs? Doesn't matter, as long as it's just text! You can have more text files for different stuff. Invent ways to use flags, prioritize, assignments, etc. It's your ad-hoc format, and easy to evolve. Heck, for personal hobby, I've had success with such TODO-lists at end of such sourcecode. For more structure, I've found Freemind cool to use. It works like a text-file, but you put everything in a graph and can spread through different files. Can even use links, colors and text formats if you like. What doesn't really work, is other people's tools, like so-called collaborative tools, SM, and whatnot. One day they'll just delete everything, migrations will fail, it's slow and unreliable. Email seems to work well enough personally, though less so with the advent of "cloud computing" (other people's computer).
