I think their are two bridge crew members where it could have been interesting if either was gay.
The first is Tovok. Having a Vulcan show its illogical to deny attraction to the same sex would be fun. The downside here is how reserved the character is, so it likely wouldn't come up all that often in the show.
The second is Harry Kim. It would have been fun for him to be interested in Tom but Tom has no interest in him that way. We'd get a few episodes, may even a season of Harry pining for him before giving up and ending up best friends. Then we get Tom trying to set Harry up with people.
I don't even think either of these would have changed things much overall.
I wish this was limited to just windows phones. My travel device, a windows laptop with a removalbe keyboard, will no longer be able to download shows. Which means no more Netflix on airplanes for me.
