I will say that it is first post I have seen by witness/development team that is relating to end user directly .(from curation curve, witness voting or reputation based system.)
Have they keep communicating regularly then there will be no perception that top witness are working for their own profits only.

Blocktrades is rather good about posting the whereabouts of what they are working on. Each week, almost without fail, there is an update post.
As for the others, it is hit or miss. Some of the witnesses put out reports but they rarely get into the topics such as you mentioned.
