if everyone is fine with other sites being pushed, then for WM you need to check out:
News
xda-developers - Xda-developers
Coolsmartphone.com
There are loads of other WM sites out there but modaco is probably the most comprehensive, XDA-Dev is the most technical (you should find an upgrade ROM in there somewhere) and Coolsmartphone is another WM news and reviews site.
Highly recommend all three!
