As I've only just set up the site with this host using Typo3, I haven't had a chance yet to fill it with any content.
It is on its way, however; There'll be best practice, examples and tutorials in each of the different options you can see in the menu up there. Eventually, I'll implement a user login and forum so that comments can be left, requests for tutorials/examples made.
I have high hopes for this site, and with any luck, the next couple of years should see it blossom into a fantastic developer resource.
As for now, you'll have to just imagine it's full of awesome stuff :)
