Here are two projects I would love to build if I ever found time to do it. 

I want a news aggregator for PocketPC written to use the compact framework.  No doubt a product like this exists somewhere and if you're reading this, feel free to drop the URL in the comments section of this entry.  I still think it would be a fun project to build.  It would have a local cache so that I could sync in the cradle with internet pass-thru, then I could read my feeds offline.

Secondly, I want a web service that hosts my RSS feeds and stores a flag on each item to indicate if I have read it or not.  Aggregators would connect, get the feed list, and display unread items in bold.  I run SharpReader on my work and home machines and I hate having to re-read posts to see where I left off.

What do you use to read blogs?  How do you like it?
