For most of the nitpicky questions about the Work and Activities section, I think it doesn't really matter and whatever you choose to do is fine for the most part, but for some reason I can't decide about putting links in the description of the Work & Activities section (specifically, I'm thinking of two links, one to a pdf of a scientific poster and one to a pdf of a nonscientific magazine article). I know they'll rarely get clicked, but maybe in the event they were really trying to decide between me or another person? Or is this totally a waste of characters?
