I made a little board game recommendation site in app engine: http://www.findanewgame.com/ - think netflix meets shelfluv for board games.
I wrote a blog post about the making of the site a couple of weeks back, HN thread is here: http://news.ycombinator.com/item?id=1811024
I'm using amazon affiliate links on the game urls; with 6000 hits, it's made $40 - current traffic is around 100 hits a day.
I'd love to hear suggestions for improving the site, measuring affiliate conversions for A/B testing, making it more social, sharable, or whether just to let it be.
What would you do with it?
