How do we promote our site?
I think targeting homebrew clubs would serve to get a very high response rate. I sent an email to my homebrew clubs email list, but I think I probably should have waited (and will resend) when we are in public beta.
Homebrew contests also seems like a high value target, though they are usually closely related to the clubs means you might just want to start with them.
We have an auto-tweeting account set up from Brew Advice. It's currently tweeting updates from the new SE site via RSS feed.
We can update the settings or do whatever. Check it out.
