Forum usage going down?

So, what do you think? Used to be hundreds of posts a day. Now many of the popular cars can go days without a post. Are the cars just beyond repair? Are people going straight to forums that only deal with their particular make or model? Is the economy improving so they are paying to have their cars worked on or trading them in? Are they smarter and searching the forum for previous answers first before asking a question? I had thought it might be a seasonal cycle, but it has been going on too long to be that. The car model forum is getting many more posts then the real cars by a large margin. So again, what are your thoughts? Should I start spending more time in make specific forums for the cars I know to help more people?
