The new channels model is going to be great 

It already has the feeling of being a member of specific communities whereas the previous channels felt more like tags on your casts

The telling point for me is that I’m now compelled to leave certain channels I had “joined” in the old model. That’s a good thing. It means community membership has more meaning and significance 

Find your community!

Sometimes I get confused if I'm replying to a person personally or to that person in a channel I don't belong to lol .. I've definitely left a lot of channels
