Social Media Value

With all of the buzz about Web 2.0 and Social Networking, one would think that we have found the panacea of a new way to do business online. The concept is one of all about "me" and not of all about the customer. I think that we have to transcend the "social" and better incorporate it into the "business". Why do we think that the .com bubble burst was much different than what we see on Twitter? Many .com companies made nothing, offered little, and therefore failed when people realized. I am a Twitter user and I like what I am able to learn from those I follow, but is it realistic to expect it to be around with no visible income stream? The sale I made through a contact on Twitter this morning cost me nothing and Twitter some processing time. Web 2.5 or 3.0 or 5.0 will have to resolve the swing from the consumer space through the social space to the eventual consumer space again.
