Tricky as while I'm excited about Star Trek: Discovery, I've been wanting to get back into Trek fandom for a while anyway.
As mentioned elsewhere, I love all Trek from The Cage to Beyond but after the death of Enterprise and Nemesis, the enthusiasm for Star Trek across the board seemed to dip. The local Star Trek group shut up shop due to falling membership, but we all remained good friends since. And I think we all found other things to be excited about (For instance, I started to invest more in my other ongoing passions - motorsports, Doctor Who, tech, etc), but by earlty 2012 I started to miss Star Trek fandom.
I started going to conventions again. (Well, I say conventions but somehow they turned into comic cons which aren't quite the same - more impersonal). I joined some Star Trek fan groups on Facebook. I joined two local groups which both vanished, before my former local group rose like a phoenix from the ashes (and became the USS Phoenix). I found the conventions that I went to in the late 90s were still running so I started going back to those.
However, fandom had changed. I left many of the Facebook groups for the sheer nastiness that came about from some of the members towards fans of certain eras. I got told with no irony that I was wrong and an idiot for liking Star Trek and Into Darkness. Some got quite nasty and insulting too, and to be honest, the mods of the groups in question were useless. I've joined other broader 'geek' groups but they've all gone the direction of Pokemon and anime (personally - zero interest), Power Rangers (zero interest) and superheroes (a bit of interest but getting fed up of superhero overkill).
I miss talking about Star Trek (and other space-based sci-fi) so I went on the look out for Star Trek forums. You are the Number 1 search result in Google for 'Star Trek forum' so I joined based on that.
So far you all seem friendly. And while there are some JJ-haters here, you don't seem abusive of the fans that do like the new films. And after all, the new films have brought in new fans. My girlfriend for one. I introduced her to Star Trek and Into Darkness, and we're now working through season 2 of TNG, with her now owning three Star Trek uniforms.
Sorry, it turned into a bit of an essay but that's my recent Trek history.
