Great, great idea!
A few comments (because this is HN):
- I'd like to see some mention of pricing on the main page. I get that it's (probably) free until you get to some sort of critical mass, but seeing that on the site would still be nice.
- Why no "about", "contact", or "FAQ" style links anywhere, so I could ask about pricing (or anything else)?
- I know this'll sound odd, but honestly, I'd like to see you have at least some modest advertising or something so that you make back your money on this.
- Last but not least, how about some sort of policy statement? Do you own the recipes I post? Do I? Just sayin'.
