Looks like a great site and will be perusing as I finish my current reading material. Any thought in a book recommendation engine or looking into amazon's api for similar items/books to integrate?
Revenue ~ $100 so far but I've barely had any real lists added (plenty of geeks have added lists saying "testing" etc etc). Now that V2 is live I'm going to put a lot of work into building a solid community around the site.
Upkeep - $0 - it's hosted on appengine which is free :)
In the long run I'm hoping to get some pocket money from affiliate links but at the moment I'm concentrating on building something that people want so I can build a community.
Using the similarity API is on my radar, I nearly included it in V2 but in the end decided it would be better to just stick to the core stuff and ship that. Any ideas on what would make a recommendation engine awesome are always welcome! tom@7bks.com
