My home is on a group of sims called 3Bears Resort (Terra Ursa Major), run by a group of hunky gay men. The 3Bears themselves are Galileo Michalski, Duir Mayne, and Stefan Box, and although I don't know all the details, I know my friend and neighbour Joseph Nussbaum arranges things to do with art exhibitions. 3Bears is focused on being a place for gay bears: there's places to live, shop, relax, a nice beach, a couple of nice residential neighbourhoods. It was recommended to me maybe 18 months ago as being a nice place to live; I came and looked around and, by golly, it was. I found a nice lot with a little waterfront and I've been there ever since. (I'm not sure I should have to mention this, but what the heck -- they're not paying me to say any of this. No one ever has, and I don't expect anyone ever will; if they do, I'll say so.)
Overall, I think it's the way that I want to live in SL -- to be part of a community that has a space for public interaction where you would actually want to interact. I know of many, many residential sims that are lovely but fairly empty -- people TP in and out of their homes, and nobody walks around. 3Bears tries really hard to simultaneously support the artistic community, and give its residents a reason to leave their houses and go over to the "downtown" plaza and see what the gallery or the stores have that's new.
