Thanks, I just learned something!

So I’m closer to learning everything.

Well, there’s a podcast, The Complete Guide To Everything, a podcast about everything.

A weekly podcast (new episodes every Sunday night) that hopes to vanquish Wikipedia as the go-to reference for knowledge about anything and everything. From North Korea to Nicolas Cage, Tim Daniels and Tom Reynolds leave no stone unturned in their humble quest to make the world a more informed place.

You’re welcome.

If you want to learn about everything an encyclopedia is much better than a forum, since a huge majority of forum posts don’t provide any learning:
https://en.wikipedia.org/wiki/Main_Page

Reddit.com has sub-forums about everything, unlike Straight Dope which discourages discussion of illegal activities.
