I would say that I'm pretty far behind the curve on 'gettting' this social media tool, but as it's still in private beta, I guess the fact that I'm on it at all makes me still technically ahead of the curve. Of course I refer to FriendFeed , one of the many lifestreaming utilities out there. Now that I've had several months to play around on it and be in the private testing pool, I can say that as of the last few weeks, it's finding it's way more and more into my regular concentric surfing circle. When you say lifestreaming tools, a number of sites come to mind. Twitter might be among them, though it clearly has other applications aside from lifestreaming. Tumblr is most certainly chief amongst them, though it comes at lifestreaming with a clearly artistic and bloggish approach.
