When it comes to social web sites and services, sometimes I think we like to talk about them more than actually use them. A recent post we did about Twitter getting half the press coverage of Facebook despite a fraction of the traffic, seems a bit indicative of this. So who is actually using these networks?

The site Brainz did some excellent overview charts of the various popular networks this week. Alright, so they aren’t actually based on any kind of real data, but they just feel right, don’t they? I’ll paste a few below, but be sure to check out their site for the rest.
