You touched some great points here! A happy user is a great multiplier. By accepting that we only have a retention of 12% we accept that 88% new users who leave the platform after short time might talk negatively about their experience with Steem then.
Considering that Steem might get some serious competition in the near future, that's quite alarming. A lot of disappointed (ex) Steem users could go and find their pleasure somewhere else.
Thanks for your support and valuable addings. I enjoyed the read very much as well! :-)
