I'm not a part of the online fandom for it either. I have one other person on my flist who watches it and we might chat about it occassionally, but that's it. That goes for most of the shows I watch anymore. I have maybe one or two people on my flist who enjoy the shows I watch as well and we'll just chat about what we liked and not get too involved in it.

SGA was the first online fandom I got really involved in and I got too emotionally invested in it.
