I have a facebook group with more than 19,400 members and I am using it for people to resteem each other and I upvote them with my team for a little reward, it's will be good if they create groups in steemit, I like groups, it's very good to improve our communities there, I care a lot about resteem option because I don't like when people resteem other just because they earned a lot but not because the post is providing value. Decentralized groups it's just amazing.
