I like the idea of locking old threads... 2 years or more sounds good. I do agree that's not the issue.
I agree that new threads are usually more important than years old threads. Actually, I am more interested in new threads than new posts to existing threads. If I read a new thread and I am interested, I watch it.
I would like to see a "new threads" area on my home page or have the new threads highlighted on the existing "Recent Threads" area. However, I would prefer a "new threads" section.
