Is there really a reason, for example, for there to be the distinction of “magazine” and “community”? When you’re federating, the same features should be called the same, if close enough. That way everyone can talk with everyone about stuff and we all immediately understand each other.
Would also alleviate confusion for any new adopters.
^I’m pretty sure this is going to be impossible though, since each sides egos will likely get in the way :D^
Channels would be a way better analogy, I think.
Magazine would make sense, if the aggregated content would be more prominent. Think Google News with comment threads bolted to each entry.
