One possibility is that blogs remain the primary social hub for many of us on the web but turn into lifestream sites that syndicate our content to and/or aggregate it from anywhere. (This is my best guess on where things are going and why I have moved my online home to Posterous () at steverubel.com.)
Everyone has communities on various sites. Twitter, Facebook, Flickr, and others have built incredible sites with poweful communities.
But ultimately you need a site that is your own… Your hub on the internet. A place with your domain, your look and feel, where you control your content.
That’s what Posterous is. Are we blogging? Are we lifestreaming? Call it what you want, but we want to be your place on the web, no matter what you want to post and where you want to post it.
