Just over a year ago I started the 'WordPress 360' project (wp360.org) which tried to achieve the same model as this website.

I closed the site down a few months ago after deciding not to renew the domain mainly because of what Alltop.com was doing and the fact that any tech savvy iGoogle user could set up the same thing.

Anyhow, I wish Darren luck with this project, the site is already more technically advanced than anything I came up with so kudos to his magnificent coding ability ;)
