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?
