In general, I agree with @erikblues when he makes the argument about how the engagement of the community should be handled through the forums and how dfinity is losing an massive opportunity to engage with community (How Dfinity is rapidly losing credibility - #29 by erikblues).
That said, there are definitely folks within the Dfinity that I have engaged with; both at the forum posting level as well as at the DM level that are trying to help. The three qualities that have stood out for me are (a) ability to listen and understand the concerns (b) ability to think about the solutions as presented; even if it contradicts their previously held beliefs and positions (c) ability to reason with incomplete information; yet communicate that fact to the community.
In particular, for me @diegop, @akhilesh.singhania and @kpeacock are exemplary in context of their behaviours in a positive sense. I am sure that I am missing others and I apologize for missing them.
What does NOT work for me is when someone in a community improvement post says that he/she is working on the topic related to the community post from dfinity and that they are listening and then they COMPLETELY disappear from engaging with the community in that post.
