Instead of answering, I went through all the responses thus far and made a spreadsheet of the answers. (This is absolutely non-scientific and possibly inaccurate, plus there's no data as to how well these strategies worked, but hey, I was curious and thought maybe others might be interested too.)
I also have a list of "Other" answers that didn't fit neatly in these boxes or struck me in some way-- I'll link those next.
