What's interesting is that from a UI perspective the "flag" is very poorly implemented. I don't ever flag and I'm sure the flagging varies also with the length of time someone has been on the site. Newbies and older users probably flag for entirely different reasons (leading me to believe that "flag" isn't even evenly weighted or shouldn't be). And what does it mean to flag anyway? It's possible someone thinks that it is "read later" and another person "this is wrong". How does anyone know what flag even is for exactly?
