I just started a small page names bitsites.net
where everybody can announce his bitcoin business. The list in the wiki gets longer and longer but is hard to search. This project is still very small and obviously took less effort to bring it up yet. Anyway I like the idea of a free collection of bitcoin sites combined with a little community.
There are many possibilities in the future. Trust rating of sites, popularity rating, discussions and user feedback for bitcoin services, etc. This is just the first step and I hope some bitcoin business owners like the idea and will join.
Please take a look, I'm open for suggestions and feedback,
