I'm sure this already exists but someone should make a forum aggregator. Read only with an open standard and make an account to join the discussion on the site. Basically just a fancy rss feed.

Creating a healthy new community takes a huge amount of activation energy or an incredibly long time. Why not just transplant the mature communities to more fertile ground? Bonus: it's much harder to astroturf an entire forum than a few high visibility accounts.

I'm sure some forums wouldn't want the extra traffic with no ad revenue. But discoverability would be a huge boost now that search engines are trying to be a black box Ai MitM. Anything other angle I'm missing?
