Replying to Subscribing to "My Threads"

Hey, I don't use the "my threads" function because every single thread I post in gets sent there, and its often hard to find what I want.

I was wondering if people thought "subscribing" to threads would be a good idea. For example, everythread has a link which simply adds it to your threads when you click that link. I know I'd love to have this functionality. This allows you to track threads you might forget about, and ones you don't post in as well.
