This is something I've been noticing lately. I see questions getting downvoted and fail to see a reason or an explanation - until I see the asker's accept rate. So, have you noticed that people with low accept rates get downvoted for no reason? Or is it just me?
I think this is discouraging for new users. It's a lot more friendly to post a comment telling them to work on that accept rate.
