I'm the opposite, I make threads to have people respond to me, and I am thread hog (in this forum I am not so much, but in others I just make threads, and I'm not doing it to spam but more because I feel like I want to have a direct communication).
I respond in threads though because I want to contribute myself into it, and if it's interesting. Some threads don't interest me, or I don't have enough knowledge to do any value for it, so I'll just read it.
But I just love creating threads. If I am on the computer I cannot go without making a thread in at least one of my favorite forums (I participate in about 3 forums on and off at any given moment, sometimes I'll just leave from a forum since I gain everything I need from it or it is just plain nonactive).
