C3 Presents -- the folks who put on events with more than 100 acts, like Lollapalooza and Austin City Limits -- have been busy taking advantage of social web services coming out over the last year, and to great effect. Especially, it says, through using Facebook Connect.

Already those sites are seeing massive growth: A 99 percent increase in page views, a 34 percent increase in pageviews per visit and a 20 percent increase in the average user's time on site compared to its pre-Facebook numbers, according to C3. What about other traffic drivers, like big lineup announcements? C3 says traffic had been holding steady this year versus last -- including when lineups for both festivals were leaked prematurely -- and only saw the surge when the integration went live.
But it's not just about Facebook, of course. C3 also introduced ways to share concerts you're going to back to other sites, including MySpace and Twitter. More than 70 percent of the traffic that it's getting from these sites is through the sharing feature. Meanwhile, MySpace is still in the process of rolling out its own Connect-style service.
