A note on the origin of this project
Brent Simmons, Author of NetNewsWire, MarsEdit, Glassboard and Vesper posted his OPML file, lamenting the lack of an OPML sharing service. That drove me to spend a weekend on Feedshare. Seemingly there is some interest in such a service. Alex Kessinger encouraged me to open source the code. I think that's a great idea and hope that others might want to help improving it and adding features.
