I was just reading the post "under vote-leave me alone!!!", and it got me wondering how other people vote on this site, eg do you tend to vote for every image you look at? Do you tend to vote more for pictures you like? Do you give a lot of "5"'s for images that don't really grab you, or to improve "karma", or even just because you feel obligated to?

Also same deal regarding comments - do you usually only give them if someone else already has etc...
