The thing is, even us ardent long-time fans do not speak with the same voice, as the internet (and this very BBS) prove every day. Even lifelong fans have different tastes, expectations, priorities, etc.
So "serving the fans"
does not mean the same thing to all of us. For some, that means being very strict about "canon." For others, that might mean plenty of nostalgic easter eggs -- which other long-time fans may scornfully dismiss as "fan service." Some folks are all about the characters, some about the science and engineering, some about the topical allegories, or utopian messaging, or whatever.
Seriously, you're never going to be able to satisfy "all ardent long-time fans" because we're a famously opinionated bunch who seldom agree on anything.
Don't believe me? Go to any thread about the "best" or "worst" Trek movies, series, or episodes. Chances are, you're going to see the same titles appearing on both lists.
For every lifelong Trekkie who thinks that TMP is a masterpiece, there's another who thinks it's an utter bore. For every diehard Trekker who thinks DS9 is far and away the best Trek series ever, there's no shortage of fans who still can't get into it -- and are quite vocal about disliking it.
Heck, we can't even agree on "Trekkie" vs. "Trekker" so why think all devoted "long-time fans" are going to care about the same things?
