Everyone else probably wrote about it, so I thought I should write about it too 
Dimitri from Microsoft released an RSS Toolkit for .NET that can be used to consume as well as generate RSS feeds.
You can read more about it in this post on his blog.
Dimitri is the development manager for ASP.NET and a great guy in general.
He actually made this hotfix for a company I used to work for (it was later integrated to one of the service packs of .NET framework v1.1, and I think its also included in .NET 2.0).
The whole ASP.NET threading model and how it works with Single Threaded Apartment (STA) COM objects is a good material for another post, so stay tuned
