Rand and his team have launched their new SEOmoz site. It includes a user-submitted blog section, where each member can have their own blog, called YOUmoz. Voting is enabled, and popular user posts will make it to the SEOmoz blog itself. That's pretty cool. They also offer a Premium user feature now, where at $39/month, premium users get access to special tools and content. I'm sure there's probably more that I haven't discovered yet, but that's what I've noticed so far (besides the obvious change in design). Will be interesting to see how this works for them.
