Workflowy sounded cool, but I've tried so many similar apps and mind-mappers and other things supposed to boost my effectiveness (and wasting way more time using them than I was actually saving, if I was even saving any) that I've become very wary of trying any new ones.

For some reason, your comment prompted me to try it, even though the suggestion that led you to post this in the first place didn't really register enough to make me go try it.

So, all this leading up to: I'll also be giving it a try. It seems like it could be a very good midpoint between the mind-bending, waste-time-trying-to-figure-out-a-correct-structure TheBrain (though I haven't tried the latest version of it, which looks like it could have fixed some of my complaints), and overly-rigid, expand-madly-into-a-humongous-confusing-blob-of-text traditional mind-maps.
