I recently was turned on to a really interesting "Web 2.0" site named Zimbio. Zimbio has taken a very unique spin on web portals. Basically, they've given users the ability to create their own "portals" on a wide range of topics. The cool thing is that any user can contribute to the portal in a number of different ways. There is a group blog, forums, links, blog rolls, picture galleries and more. Each portal has an AIM-driven chat room as well as IM presence indicators for each contributing member of the portal. I believe this is the future of "portals": online communities of people aggregating relevant content around a certain topic. This blurb certainly hasn't done the site justice. There is much more here than what I have covered. The community seems to be relatively young (I believe they just left private beta) so go visit and find a topic to contribute to and discover the future of information portals on the web.
