I think bitcointalk will not die even if there are no more campaigns here. Bitcoin users are already ideological and this is where Bitcoin was born. Even though I haven't followed the campaign for a long time, the discussions on this forum are quite interesting, I'm still here and not yet interested in altcointalk. I don't know the future...
Apart from that, this forum is also not intended to make a profit from advertising so it doesn't matter if there is a slight decrease in traffic because maybe this forum is dedicated only to supporting bitcoin, not for profit like altcointalk
Even with all that you have said, we still can't deny the fact that signature campaign here are the major cause of the high traffic and I could bet that if anything was to stop the participation in signature campaigns then the traffic would certainly be dull compare to how it was before. Although I know that this community has gain so much population and popularity and also I agree that discussion here are on another level but the truth is that signature campaign are major core of its much high traffic and that's the truth.
