Sitting in forum and writing posts or answering some questions is a work & we should understand this.
It takes time out of coding, out of concentration..uninterrupted mind..
Personally I wouldn't mind that developers are a silent, though in resent days they do answer a lot of questions.
I believe they are trying to get into conversation & this pool is a good example..
You might say it's not perfect, it could be done better - in the end is not the conversation that matters,
but the product. Think it's enough they read everything.
What do want from Them more: software solution or answers. Me, personally I'd choose software..
As for the features, I do believe the road-map is already laid out & they probably have their own thoughs,
and/or technical reasons on what is the best way and sequence to implement features.
So maybe, let them do their 'poetry in code' trying to keep them out from this forum?.. - just a though..
