This is why I enjoy helping people on forums: I get to chase down a bunch of rabbits, drop my catch in a neat pile, and go chase squirrels for the next person.
When I'm chasing my own critters, there's all sorts of keeping track needed at the end that I'm not so good at and don't much enjoy. Plus, my attempt at a solution -- having multiple places to record stuff, so that nothing gets lost -- is part of the problem, because I go to look up whether I already have a source or not, but I don't remember where I should be looking.
(In theory, the offline/local file is the primary storage location, since I don't need to worry about preserving anyone's privacy or violating copyright. In practice, FamilySearch's Family Tree ends up as Step One, because 99% of my sources are there, and about half of them have stray auto-profiles associated with them that need to be merged and cleaned up. WikiTree is my "final draft", but it's in third place: what's here is as complete as I can get it, but there's a lot that ain't here yet.)
