Re: Perception.
Sometimes the downvotes are interesting. Particularly when someone takes the trouble to waste 15 minutes of their life downvoting your posts one after the other. That's downright fascinating. One hopes, this being an IT site, that they've written a script to do it...
On the other hand votes can counteract the echo-chamber that many internet forums become. For example: It's still kool to hate Micro$oft, apparently. However even if 90% of the comments on a thread are on that theme, a comment that's a bit more balanced will often find more upvotes than downvotes - even thought the composition of the thread would indicate to the contrary. I guess that means there really is a silent majority. Many people just don't enjoy an argument, which is fair enough.
Plus, I'm always willing to upvote a good pun. Or even a bad one.
