Microsoft have refreshed the look of the IE Add-ons site and integrated the site with Windows Marketplace.
You can go there directly at ieaddons.com or from within IE7 (choose Tools->Manage Add-ons->Find More Add-ons.)
While you're there, take a look at Tony Chor's (Group Program Manager) favorite IE7 add-on, the NewsGator Desktop Synchronizer, which keeps the IE7 RSS feed list in sync with the NewsGator Online list. This lets him keep the same RSS feeds on his work and home computers as well as giving him a web UI to read feeds.
