Because I live a mostly reactionary existence on TFF these days. I check TFF for posts/threads of interest and not check TFF for what would I like to inform people about today. In addition, my goal is to inform generally and not entertain. The amount of material to inform is significantly less than entertain, especially after I run it through a worthless or pointless internal filter. If I feel it small, insignificant or just simply doesn't need to be said I'm not going to say it. That only changes when I'm really excited about something that I feel others might be as well.

So that is my reason. Create for purpose, which is generally to inform. That was the case when I joined as well. It was rare for me to create a thread. I just replied to existing threads to join a debate or answer a question someone had. I've done pretty good just doing that since I managed 6000 posts the first year I was here.
