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!

I've been going through all the channels I'd followed a bit at a time and deciding if I wanted to stay or not because it does oddly feel like there's a bit more weight to being there now.
