Negative: Little horizontal communication, information is being lost in the mass noise, quite high barriers to entry – to keep up ( due to decentralisation nature?) maybe be lots could be learned from twitter algorithms creating self-sufficient clusters.
Also improved navigation of actual content as well as integration of all the steem blockchain projects within each other, not as they seem now as stand alone, especially with all the new ones coming out.
UPD: Actually, on second thought – reading thru the content, discussions, finding the right followers and clustering around like minded people, makes it rather more human and allows to have a personal journey. AI and algorithms might help mass adoption, but with like most things going mainstream, there is a risk of losing the truthfulness. So balance is key, to achieve it, the communication is a real virtue and must-have for community to prosper without losing ourself.

Positive: All issues have the potential to be heard and therefore solved by this community and keep flourishing.
