I have seen Scoble refer to Channel 9 in several of his blogs, but Jeremy over at Ensight finally posted the URL to get me there. Channel9 is different/interesting/cool because of how they are evolving the true blog experience. What exactly do I mean by that? Well, instead of blogging by writing posts, the blog posts themselves are videos.
The comments are still written (now wouldn't it be interesting if you could leave a video comment?) and people seem to be posting problems with the general site, but overall the site is worth checking out. Having been playing around with Sharepoint internally at my company, this site really looks like an extranet of a Sharepoint site, but I could be totally off-base.
