Shall we designate specific content to be developed? Obviously there will be plenty of user created guides that will be made but things like comprehesive and interactive skills/items/demigods information stores. This way we would avoid two different people working on the same information.
We'd have to speak with Chirmaya and Sol Invictus to organise it on demigodguru.com 
The next thing I'm aiming for is an interactive hero designer similar to the one on the DOTA website where you can walk through the leveling up of your Demigod and see how different items will effect your build.
I've written the databases I'm currently using for the items, demigods, etc with this in mind.
