Bob Cringely ponders whether or not social networking is destined, like CB Radio, to crash and burn.

I think social networking will be around for a while, but its popularity's going to dwindle some over time. I find it to be a bit of work to keep up with too many different people on too many different sites these days. Even though I still have an account on LinkedIn from years back, I don't think I've logged on there since '06, because I can't think of anything I'd be interested in there that I can't get from another virtual location. These days I gravitate more toward tools like Google Reader that can aggregate data from bunches of different blogs and other sources these days, and anything that can't be pulled into such a site gets left behind.

What do you guys think about the proliferation of closed social sites on the IntarWeb?
