NS is pretty pointless, but the reference regarding other social sites was aimed at people posting shit like: "what are you up to" when a simple PM, text, call, or something would suffice compared to something for the masses to see, not blogs and shit like that. Something comparable, other than about 90% of the interactions on this site, would be people posting pics of their gear for sale in the public picture galleries when a perfectly decent alternative exists. All that shit does it cause clutter and dilute what little substance exists.
Oh, and b/s/l?
