But I found someone who doesn't.
Earlier today I was checking out Hacker News, a really great site I visit almost daily, ran a post linking to a blog "Facebook Is Really Not That Special" which successfully pulled me and many others in. The writer is Matt Maroon, a blogger I hadn't read previously that proposes that Facebook and the rest of the Soc-nets have limited value and scope.
Of course I immediately visited the site and posted a few comments, because as I see it the social network phenomenon is a fundamental transformation of how a significant market connects to the web.
My view is that you can't simply dismiss this phenomenon as un-important. I suggest that you read his blog and weigh in.
