Agreed. I really hope (and honestly think) that third party tools (and Boost particularly) will improve discoverability as the ecosystem grows. Being able to see other servers' communities and Local feed will be a big step toward getting across the usability hurdle and getting more people here.

"Multireddits" (for lack of a better word), too. Maybe call them "community bundles." I'm subscribed to like five different (functionally identical) Star Trek communities, for instance; being able to group them all together and suppress/merge crossposts would be fantastic.

At least on Liftoff it's incredibly easy.
