I've used neo4j for a project a while ago. Once you got past the documentation, it was cool to work on and see data transactions happening without having to write code for processing RDBMS data. I haven't looked at it or used it in a while so I can't speak to their current state, but when I used it, they had a bit of a learning curve for getting up to speed. Particularly, some of their code examples were a little off so I had to spend a couple of days researching to figure out why the project compiled but nothing ended up in the database.
