It sounds great to have "communities", but the mechanics and structure have very little appeal to me. I love Steemit as one global community. We're strong that way.

I won't be going out of my way to engage in any feudal guild systems that have politics and censorship, unless it's a special niche I can meet others through... and as long as I don't have to pledge their fraternity or be overwhelmed with rules.

@oldtimer's point above was perfect. We at least have the choice to engage in those on the bright side.
