I once had some bozo accuse me of trying to "get my post count up". I still don't understand who would care about that, or how that would matter. Unless I look, I don't even know how many posts I have. A mod can remove 3,000 posts from my "count" and I wouldn't even notice. I never knew getting you post count up was a "thing", but I've read more than one person accusing someone of that over the years. Are there websites where this actually matters?
As far as the "Thanx" feature, I know many people don't like it, but I think it's great. There are many times when someone says something, it's not really worth typing out a post saying "Yes, I agree with you", or "That was kind of funny". It's also not really worth clicking the rep thing and saying "Yes, I agree with you", or whatever. Sometimes, you just want to give someone a nod, and clicking the "thanx" thing is perfect. It's like sitting in a room and someone says something that isn't worth sitting up and saying "Yes, what you said made me chuckle". You sometimes just want to give a little nod and smirk and then move on.
Click "thanx" if you agree. Or if you don't agree. Just click "thanx".
