Well, I try to for one....but the minute I get into a bad streak and I begin staring at the W/L record that is caving in on me....it gets to my head. I respect the ones that do and can do it without it getting to them. I guess its one of those things where if you can't play and deal with the W's and L's......maybe you shouldn't be playing at all.
Other people have no real life where people respect them and they post their W's only here to try to get someone to pat them on the back, something they rarely get in the real world. They want to mean something to somebody. In that case you either love their ego or feel sorry for them.
Finally, there are others who get into a bad streak and fear that some honest soul is tailing them and taking their money along with theirs. I know I've fallen into that category.....hoping that no one is cussing me under their breath.
