Sitearm Madonna has a great set of high-res photos from SLCC 2011, shot by Richard Finkelstein (SL Leko Littlebird), like this one above, with Rod Humble talking about the future of Second Life. One thing you won't see much of in those photos from the Second Life Community Convention: People actually using Second Life. I've been to four SLCCs so far (2005, 2006, 2009, 2011), and this is the first one where I noticed a serious lack of SLCC attendees logged into SL, so they could share the experience with people in-world. In previous conferences, it was pretty typical to see a number of laptops propped open with SL running for this very reason. Maybe it's just me, but this year, I genuinely didn't notice even one of them, certainly not at the major Linden keynotes, where they once were out in force.
What's the deal? My guess: Social media has totally supplanted SL as a communication channel in real world contexts like this. While you didn't see many (or any) SLCC attendees logged into SL, you did see a lot of them using smartphones and tablets to send Tweets and other social media messages about SLCC to other SL users who were also on those networks. If I'm right, I'd interpret this as just an inevitable adjustment, since social media provides an easier, more effective, and more portable many-to-many communication platform. Now that SL's web profiles are easily linked to Twitter, we'll probably this shift even more.
Just my immediate take; would love to get other views from fellow SLCC attendees. And be sure to check out Mr. Littlebird's photos.
