I actually think having 1 person is counter-productive....1 sim person (even one representing the community...which btw, isn't entirely realistic as the community itself is heterogeneous) is going to be out-numbered by the other folks. I think people in sim community need to step-up as individuals, follow each other, like the posts, re-tweet things they agree with, etc. It's more of a numbers game....they start seeing posts from sim guys that are getting 100s of 'likes' and 'retweets'...it might begin to carry more weight.
Grousing about things here in the OS forum isn't going to do anything.
