Being new to SteemIT, I wasn't here during the heady days of community. Seems to me that's one thing that's really lacking is a good means to interface by interest groups. The main site seems to be geared less for curation (which would require some level of automated searching and filtering capabilities beyond just trending/hot/new and tags) and more for curation reward acquisition. It will be interesting to see where things go and if anyone steps up in the inner circle or among the outer circle to enhance what's lacking.
