Sam is right, and it would not take much to do this. However...for whatever reason, most FOnline developers have had the opposite method: stay very quiet about all work, and surprise us.
So some people might agree with your suggestion, Sam, but I believe you're fighting a mountain. Spoiler: mountains always win.
That outcry is misleading. Some people cry and complain. Meanwhile the rest of us love the game, and now even more in Season 3. We're just not as vocal, so the general impression is "everyone hates it". The truth is, most ppl love it - only a tiny minority hate it. Of course when i say that, i'm including the hundreds and hundreds of ppl who tried this game and left due to the overwhelming proportions of total jackasses.
Back to your idea though: last season i suggested to Kilgore that, as a wiki editor, i could manage some "wiki leaks" about current/future development. It would not at all be comparable to a developer blog, but might help to bridge some gap between whatever they're working on and the total silence we inhale here most days. I think he thought the idea was cute, so maybe i can eventually be trusted to share some specific tid-bits of dev work in advance. Don't count on it.
In the meantime, embrace the mystery! Hang in there - i do believe work is being done. Free game though, so no ETAs, no schedule, no dev blog, no promises, no revenue stream, etc.
Back in the days of 2238, Rotators did establish a dev blog. I remember at first they used it and shared info, but very quickly it fell inactive. It was always my impression that it was due to the jackass community, who would read info there and immediately start complaining they did not like upcoming features. So maybe those devs said, "Fine, then skip it" and abandoned the dev blog idea so they would not hear such complaints. If so, it's understandable that method has carried over to today.
