Is there a "cranky old man tag"? The OP just seems to lack vision. This post is along the lines of the old "everything that will be invented has been invented" saw. Social activity / interconnection of the twitter/facebook type is just in its early days. To say that we somehow fully understand everything that will arise from that, just 4-5 years in, is amazingly (if not link-baitingly) shortsighted.
