"As a special limited-time promotion,you can get free sugar and cream packets with your coffee at participating 7-11's when you say 'I hope I don't spill this on the CouchDB.' The promotion is not supposed to start until tomorrow, but I just tried it and it works already."

+1 about the promotion - totally works ;)

I've been playing with CouchDB for a few weeks now. It took awhile for me to rescript my brain from years of relational databases, but now it's hard to look back. The sheer flexibility and the siren-call of map-reduce is hard to resist.

There were a few things that helped me get my head around using CouchDB:

First was the CouchDB screencast from PeepCode: http://peepcode.com/products/couchdb-with-rails

Second was an article that helped me understand how to 'join' different types of documents: http://www.cmlenz.net/archives/2007/10/couchdb-joins

Third was this discussion that explains how/when to divide a document into sub-document-types: http://stackoverflow.com/questions/147837/couchdb-modeling-f...

It's been fabulous to play with and I'm building a merb app with it at the moment - very fun. I'm looking forward to it maturing into having camps, books, conferences etc... (here's the first book announcement: http://books.couchdb.org/relax/ )
