It took me around a day to notice... but after I installed IE8 beta, all my RSS feeds from my "Common Feed List" stopped updating.

As a result, a few things have happened/I have noticed several things:

• Outlook 2007's RSS folder deletion sucks.  I created a "temp" folder, and dragged all my old folders into the temp folder, then deleted the whole temp folder.  Result of design by committee: Your product sucks at very simple tasks because not all use cases end up being included.
• RSS feeds are background noise.  And after a day or so, I "miss" the noise.  Makes me wonder if I should be spending more time on important things instead of reading all this "news".  RSS feeds are a form of noise pollution in my life.
• I manually re-added the 8 or so feeds that I actually need, into Outlook 2007.  Reddit and Digg are both cut, due to the poor signal to noise ratio.
• IE8 opens a lot more connections - and loads sites faster.  Also mentioned here: http://www.ajaxperformance.com/2008/03/07/ie8-the-performance-implications/
• Outlook 2007's RSS functionality is... decent... but still leaves much to be desired.  I have 3 machines, each with Outlook on them against my Exchange server.  This means that most of my RSS feeds come in THREE times over.  Who decided THAT would be a good idea?  The committee did.
