I think theymos should continue to roll things out at the pace he feels comfortable and not be pressured by community members to make changes. I also think his time is likely better spent elsewhere then doing a newsletter.
Of course, theymos should make decisions based on his own considerations, but I think his goal was to create a communicative fellowship capable of offering and arguing new ideas related to improving the situation on the forum. And it seems to me that theymos succeeded, since a huge number of different proposals in the Meta branch from the side of the participants are proved by the fact that this forum has a large number of not indifferent users ready not only to offer qualitative changes but also to participate in their implementation.
I don`t think that bitcointalk members are pressuring theymos by generating new ideas. On the contrary, they are all eager to help him make the forum even better. In addition, theymos makes decisions as objectively as possible, analyzing the situation "from above," while user suggestions are based on an analysis of the situation "from within", because users are directly identified in the community, they see the forum problems from all sides, they better know and understand them. Theymos should be glad and proud that the forum has become a place where people want to come, where they want to communicate and share their thoughts. And users want not only to preserve these dignities, but also to multiply them.
