Portlets - AI, ML, VR & more

I loved publishing comparison among portals and on this website I found another one. Here is the comparison, this time between Liferay Enterprise Portal and uPortal - Liferay vs. uPortal Also here there is a very good comparison among all popular open source portals i.e. Sakai, uPortal, GridSphere, eXo, Liferay, and Stringbeans.

Analysts had long predicted the emergence of collaborative portals. Most of the leading vendors grabbed their research by both hands. IBM integrated its portal and collaboration software into one product called IBM Workplace. BEA acquired Compoze and Plumtree to achieve the same (though we have yet to see an integrated collaboration product from BEA. Perhaps because BEA lacks a product similar to Lotus Domino in its kitty.) Rest of the vendors too tried their best to take advantage of collaborative portals and now we can see the collaboration/ team feature in nearly all leading portals. In IBM WebSphere Portal it is called Virtual Portal, in IBM Workplace it is Team Spaces, in Sharepoint Portal it is called SiteArea and in eXo Platform it is called community and so on.

I would love to see what all other changes are there. For example I would love to see and better AJAX based look and feel. Check announcement here.
