I've been in the chat for 3-4 days now.  Unfortunately I see why no one joins. 90% of the chat is plagued with utter nonsene, but 10% of the time you actually see people discuss 3D. On a business level it's not right to use Rendo's chat room for your personal discussion, the chat is there for renderosity & 3d related discussion not to talk about how about how much you love your cats. Don't get me wrong, there is nothing wrong with that casual talk sometimes, but when 90% of the time people discuss nonsense it's no good.

The solution is for renderosity to either enforce 3D only discussion or create a separate chat room for "casual socializing".

I'm still going to go into the chat but most likely start blocking people with  no desire to improve their renders, who don't care about the quality of their renders and only use the chat to talk about justin bieber.

However there are some in the chat room who do use it properly so it's not a total waste. You just have to filter out a lot of worthless chat.
