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!

Is the desktop experience way different than the mobile experience when it comes to channel. I find it challenging to navigate on mobile (particularly since they removed the band of channel bubbles across the top of the screen) but maybe it’s just me.
