It’s very interesting to view the rapid succession of niche-finding of the various social networking sites, and the variety of sites that fell off the face of the earth after the newbies became the big kids on the block. And still, many of the big brutish kids on the block get shoved aside by younger, smarter kids.

Even facebook.com might not be safe – remember when everybody thought myspace.com was too big to fail? And, certainly, it hasn’t failed, but it has definitely been eclipsed by facebook.com. Now twitter.com, seemingly one of the simplest, ridiculous concepts for a website possible, is growing by leaps and bounds. It’s very unpredictable, at least thus far, which makes it such a challenge for marketers in terms of harnessing their potential.

I’m very interested to continue following the development of all of these players.
