I agree. When the site opened there was a "Mission Statement", someone quoted it in a discussion here.
That must have been written twenty+ years ago and up-dating it might, in itself, be good publicity.
Re-iterating some of the founding principles and giving some sort of agenda for the future would at least give me some confidence that The Management anticipate there is a future for the site. After ten years here and noting the lack of response on many issues, it sometimes crosses my mind that one one day I might try to open ebid and find a "We couldn't find this site" announcement.
I've said before, when replying to threads about proposed improvements, that I'd be happier to be told that an idea is a non-starter because of cost or time factors. Rather than it being ignored. At least I'd know and could make sensible decisions based on facts rather than existing in limbo.
