I don't agree there is much unfriendlyness to newbie generally here. Compared to other forums I think it's actually quite civilized and friendly.
And asking people to search and ask proper questions is just basic forum etiquette.
The problem as I see it is that newbies wll read about things like running Debian or cloning to SD without realizing that those things are actually advanced hacks.
Personally, I'd've rather have seen the Tablet School name leveraged. It's already known and respected, bringing it in under itT proper seems like a reasonable plan, but I suppose you guys have discussed it.
A good wiki is the answer. And if another site is needed, it seems to me that it already exists -- the Tablet School site.
