Personally, Mongo maps so nicely to Ruby that sometimes, I just use the regular driver rather than an ORM. A database that naturally understands hashes and arrays is lots of fun.
Also, it seems like with Mongo, I can often design most of my pages to need just one query, and therefore they're crazy fast. This might be possible with other NoSQL stores too, and I'm trying to get more experience with more of them.
