Needs more resources!

I'd love to see tutorials that really spoon feed sharding and scaling it in various scenarios. The docs have a simple tutorial but it's brief and relies too heavily on "you'll understand it if you just do it". I want to use MongoDB but I don't want to wake up 3 months later and discover what I did was screw it up.

I'd also love to see articles that talk about what can go wrong and how to recover from it, and maintenance.

Generally just stuff that would prepare me and others to use MongoDB coming from no experience with nosql stuff.
