First off, thank you very much for putting in the effort of developing a proper Ruby client for Couchbase! Your client is what saved Couchbase for me.
Now, I guess there are a lot of people who use Ruby with the old Couchbase Ruby client and don't even know about your work. A while ago I started a thread on the forums where many people are complaining about Couchbase's lack of Ruby support. I think it would help a lot of people if Couchbase would link to your client in the official docs.. maybe you/we can get them to do that somehow?
