Sites like this are proliferating rapidly. I would also point you to
Cold Fusion-based solutions. Two examples:
http://www.allaire.com/support/ (go to Developer Conference)
http://www.citypages.com/ (go to Join Discussion Group)
I am not affiliated with Allaire but participated in the construction
of City Pages.
Cold Fusion is an NT development tool for web-database integration,
developed by Allaire.
