Steve Rubel, the man who once famously appeared in a BusinessWeek cover story titled, "Blogs Will Change Your Business," is no longer blogging. Well, ok, he's lifestreaming, which to a layman basically means you can expect shorter bursts of content aggregated from social sites including FriendFeed, Facebook and Twiter, as opposed to solely blog posts. The move is significant, as Rubel is the first high profile PR blogger to move to a full lifestream format. (Please correct us if we're wrong.)

As he wrote in a post explaining the move:

This site will become my primary publishing hub - my new home on the web. Meanwhile the spokes will become the social networks and platforms where we all spend time. Today that's Twitter, Facebook and Friendfeed. Tomorrow, who knows. My old site will stay online for the archives but I will not be putting any more content up on the old site...After five years of publishing, this seems like the right thing to do.

Rubel stresses that he doesn't thing the blog is dead, "However, the blog format needs a reboot," he said.
