by your definition of dead, yes this forum could see more usage. yes you would be missed, as anyone would be that is trying to add to this forums content. usage depends on member involvement and use. this forum has its popular threads and ones that (as Vulgar said) just get read. although it would be a better situation if for every thread / post, there would be more discussion in the topic being posted.
if you don't feel your opened threads are getting the attention you feel they deserve. maybe try to break down some barriers and try for some more controversial subject matter. editing and writing in a forum can be time consuming and bothersome i know, but how about adding more eye candy (pics), links and further information to talk about within your threads.
just remember to keep the forums clean of hate, pirating, nudity, spam and illegal subject matter.
also there is alot of good threads that have been buried. try going back through the forums and reviving old threads with still relevant subject matter or your opinion on what is posted.
