I mostly give meaningless comments XD Have been on deviantart for way too long and eventually reached a point of only generally saying nice things or not bothering at all as previous interactions have led to precious little rockstars having the text equivalent of a hysterical screaming meltdown and sic'ing their white knights on you for daring to tell them anything other than how amazing and perfect and wonderful they and their art is. Decided after a while I had better things to do than deal with that and kind of fell into a habit of being totally boring .

I don't particularly like getting criticism (used to think I was pretty good at receiving criticism but I don't think the amount of excuses I made for what was getting criticised counts as being good at receiving criticism) but I don't discourage it. Will only offer it if asked or if the person either has a history of or seems like they could handle something other than a "nice post" style comment (or "wow awesome work" style comment as it usually is on dA XD).

I think it takes some serious guts to call out behaviours especially on people you really like, but that way you can tell the really good friends? Obviously you and the friend in the story are :D
