I think an offhand "woohoo, Georgette Heyer is sublime!" type of thing which doesn't require much discussion should be fine on the board. It's the in-depth, let's discuss every episode or chapter or whatever in detail that should stay on the separate boards. It's just somewhat tricky to decide what that should be.

Yes, there have been lots of uncomfortable political-type posts on Read and Find Out. But there were just as many on Wotmania. We just see them more because there are fewer spam posts now. I kind of prefer it this way.

It'll come together if people want it to.

Don't forget: it's always hard to let go when someone's wrong on the internet!
