Not really. Maybe I just don’t care. I add my two cents (sometimes three) where I feel like it and move on. If I check back and there’s a reply directed at me I might talk some more, depending on what the comment is. I don’t really feel unappreciated though. In the past users have sent me PMs thanking me for an answer, but this doesn’t happen often and I don’t expect it to. If you like it, good. If you don’t, oh well, read the next one.
I do think lurve is a way of showing appreciation though, so when I read an answer I think was helpful I give them a GA regardless of whether or not I asked the question.
I’d just like to note that sometimes it kind of bugs me when the joke answers get more lurve than the legitimate answers. I’ve given the jokers lurve, but not without giving the helpful people lurve too. But, eh, so it goes I guess. /rant
