Thanks for sharing my opinion about retention on HIVE, as I share your opinion... 😃
Also, I would add that @stekene's comment is on the spot! When we joined HIVE (pardon, legacy chain) we didn't have communities and it was an even bigger mess... But today, we have them and they are playing a crucial role in keeping users active! You find people who are similar to you and there is no way that you will quit! Firstly, you will enjoy posts and conversation, and secondly, they will not let you go! 😃
