I'm on OP's side of this discussion as well. My favorite dev. community is HL2 World and I post all of my design there because I see it as a more helpful place, critically. I've noticed that Interlopers is the place for technical, how-to tutorials but I'm not interested in those as much as how I just want to post a screenshot to see if others can spot any flaws. A little more on the communities, and using the popular opposite again, I know HL2 World is a different mindset to the outlook of design and output of motivation. Most of the work posted there is so much more casual than the forums here.
It's almost as if this website requires some unnecessary fantasized standard from its users to post a thread (look at the portfolio forum -- I mean... really?) This place seems like people try too hard to be 'professional' when it clearly isn't. Setting the mood and co-op environment through a message board isn't as great as it may sound when it just doesn't work. I have to point out that MapCore is more believable in the e-formal aspect for me since there are a handful of users who actually are in the industry and who really do frequent it more on terms of casual individuality instead of this wannabe work-place ethic. And ModDB's bunch of regular posters are a borderlining joke.
I haven't stuck around here for long but I already know which of you are most likely to say 'Nice job!' in a thread just before leaving it, not that that's so bad. I'm not even sure if they ask themselves the benefits of their post when the author clearly frequents for criticism. My motivation to complete a project comes from the 'grosses,' not the 'looks awesomes.' Of course it's courteous to assure others that they're on the right path when they question themselves or need the support but I could only take a 'nice job!' seriously if somebody were standing behind me or playing my game in-person and speaking on impulse instead of taking a minute to click the reply button and type it out. The differences in seeing a 'nice job!' on somebody's face while playing are incredibly different from being typed out, as you could have guessed.
I know I'm being fault-finding and cynical -- I wish more artists would be as well. Remember that you don't need three paragraphs to tell me the superficial flaws of my screenshot. Just reply with 'gross' and I'll love you long time.
