I just found osliving.com which is a beautiful site listing open source products. It's nice to see someone collecting open source products with a nice packaging. Much to often sites like those suffer from the same usability as a command line prompt.
I found it through a referrer as they (or someone) have added umbraco - so go find some nice oss inspiration and while you're there add a (nice ;-)) review of umbraco.
Kudos to Brian Vought and Andrew Eglinton for creating the site.
