We've already changed the old "stack of boxes" design into something more fluid, and "imported" some sidebar features from other wikis.
In general, I'd like to add more "community" features to the page, such as an input box that lets people create articles about their favorite GW web sites or videos. All blog posts in Category:Community blog should be listed someplace prominent, too.
How about relegating the old "List'o'Links" to an "information portal"? Of course, the community portal might be part of this redesign - do we need 3 portals? One for readers to get active, one for editors to use, one for finding stuff?
