You might consider registering your account (if you might participate more -- I've been finding this a great place to learn interesting math). Nov 19 comment Combinatorial Morse functions and random permutations @Liviu: I like your question and have been meaning to think about it for some time now, but never seem to have the time. Meanwhile, I hope you don't mind that I added an enumerative-combinatorics tag to it, in case that might draw some additional other people's attention to your question. It seemed to me at least like an interesting relaxation of counting alternating permutations.

Nov 16 comment When can we determine an $f$-vector or rank-generating function from its unordered list of coefficients? Richard, Thank you for your thoughts on this. I was also wondering about complexes with convex ear decompositions, but will need to spend some time with this. By the way, one reason I was quite interested in the question I linked to above is that I've been trying to figure out how to do some things in a way that'd be sensitive to field characteristic, and it seemed like an answer to that question might help.
