I think it's a good idea. This forum is a target too easy for whomever may decide to do a crackdown on coiners (which I expect soon or later).
Regarding noobs, if they learned to open a browser, they can even learn to launch Tor Browser. It is time they do.
A major drawback is that the .onion network is slow as hell, and there is little hope that it can improve much.
If more people ran exit nodes or even internal relays Tor would be a hell of a lot faster, but it's the same as Bit torrent, people just take and leech off the community and never give anything back.
You do know running an exit node is legally draining and can put you in jail, I don't blame people who don't want that responsibility.
