I don’t think it’s weird. Right now it probably isn’t great cause the pool of commenters is already small, and this dilutes it further, but I think in a world where we had plenty of people in all those communities it would be fine.

It does suck on the posting aide, though, and it also seems like there might be some use to a tool/feature that merges them somehow so you’re viewing it all together and respond to whoever you like in one place.
