The reason why I dislike MongoDB is because it exist in between that key+value store and ful blown database. They market is as the best of both worlds, but it ends up being the wost of each world. Its like all those car+bike, car+boat, car+plane, boat+plane, boat+bike combinations that have been marketed over the years.
If I had a bunch of keys and values, I'd put it in memcache. If I had relational data, I'd put it in postgres. I don't see where mongo fits into play. Every time I've seen it used in production, it always seems like its being used as an improperly implemented RDBMS or an improperly implemented key+value store.
