Thanx for response! I don't personally see too many communities forming as most of them seem to be just some "use tag, may get upvote resteem". I would rather see those as some groups, rather than communities as they seem to be very isolated from one another and there is no bleed out to other content from them. I see the problem being that most of these groups are to support creators only, and people are giving up their curation because they feel demotivated to do it them selfs.
