I'm enjoying it so far. I do think it encourages more discussion and a greater variety of topics and opinions in one place (less of a hive mind).
As the platform grows, some communities will probably end up splitting up into more specific / popular areas. Hopefully that will happen naturally though, when those breakout-communities are big enough to sustain themselves and keep things interesting.
But for now at least, Beehaw's definitely got the right idea. :)
