I've never given xper a second thought when answering a question. If I answer a question, it's because the question drew my attention somehow. Xper is just a bonus.
I've never really given thought to the idea that there might be people out there who are just in it for the points, but the amount you get is so tiny that I feel there are far easier ways to get twenty bucks in far less time.
Of course, it's very easy to see. I'm pretty that that, and the growing community, are the reasons why the value of the rewards has gone up, and the Xper points you earn for just about everything have been slashed.
I have seen some phenomanally stupid "opinions" on here from time to time.
Like there was one question, asking something about what guys think is meant when a guy is called 'cute' versus 'hot' or something. So naturally someone had to pop in just to say he's not gay. Which was not helpful in the slightest.
