Certainly there are a lot of websites and communities where we can promote our SE and hope to gain more users from. Can you suggest such websites and communities here, and possibly help spreading the word about this SE?
Langauge Log has a fairly large readership, but a plug for the site there might open the floodgates to trolls.
My favourite language related site is languagehat
Someone mentioned us there last time we were announced on Linguist List (when we still needed commitments to launch), but I don't think I've seen a mention lately.
