Play Framework Mongodb

I've been learning new stuff like rails and mongodb ( wow ) and a bit of node.js. BTW, you know meteor framework ? You should look at it just for information. Well i dislike rails, yes it's kind of easy if you have a small project, if you do something bigger it can get you dizzy ( at least to me, with C and then C# background ). So i looked at JAVA and now i've been playing with play framework. What a breeze, nice enough docs, easy to learn, easy to code, lets see if it's easy with a bigger project. So far, it works, you follow the tutorials and it simply works. KISS style.
