Great idea for an experiment. Thank you for conducting this as well as writing the results.
Steemit need more and deeper interaction, and less spammy/worthless comments. I hope your posts inspires many people to put more thought into their responses so that they can be rewarded and so that steem can become much stronger.
You are right @danpaulson.
With the amount of comments per post (under three) the site is in dire need of more commenting. The numbers are even worse if we took out all the spam bots that operate on here. I imagine we probably average about 1 comment per post, a comment made by a real person that is.
