if you are using sharepoint (either portal server or just the windows sharepoint services) and want to list some news feeds on your sites...check out my rss feed web part for windows sharepoint services.
i wrote a little web part that lists rss feeds in a single web part view. some features included: cached results to avoid continuous http requests (configurable duration), proxy server support (except for user auth proxies), description preview, date sorting, etc.
check it out and let me know what you think...given the whidbey stuff, this should work in asp.net whidbey as well!
