A lot of people are dogging acconrad, but I have to agree with him. I was having a problem with rails, and I found the answer on stackoverflow. The right answer had no upvotes, so I figured I would upvote it; this way the original "asker" would know it is the right answer. However, it said I didn't have enough rep to upvote... I'm sure he'll figure it out but this would save him from checking the other "solutions".
Hey, let’s all downvote alexsherrick and tell him he’s an idiot for not understanding site policy instead of recognizing that he is pointing out an undesirable effect of that policy!
