Sure it gets slow sometimes, but there are so many threads that are joined by new folks and contributed to on a daily basis (just look at the list and the dates they've been contributed to!), I'm not sure if it can ever be killed.
I'm here regularly and am often surprised at how many new people actually appear and comment whenever I post a new topic.
Sure, it's a bit slower than a year ago or two years ago, but, don't forget that there have been a couple of new releases recently (SoM and DD-I) that people may be trying out. They'll be back though. We Skyrimmer's always come back, but, unlike some gamers (DD-A an example), we do like other games too!
It's just the Skyrim is our favorite.
When Witcher comes out next year we'll probably lose a few people for a little bit and then they'll be back.
Personally I love this forum. It's not full of cliquey, know it alls that will tell you your stupid if you don't do it their way. I hope we all try to encourage and help each other. I know that's been my experience.
