That makes way more sense!
The only roadblock I see is how difficult it is to follow communities outside your main instance. It would be nice if there was a log-in-as option so you can easily subscribe if you come across a page that isn't a part of your instance. Right now you have to either search it on your main, or copy the url over (which I've seen doesn't work all the time, but could be because of server load.)
Think I may just leave the subs I moderate down for longer, then.
