I lurk for much the same reasons above, most of the time I don't have anything new to add. You can now file this post under the most ironic section.

Also, I seem to have an unique ability to kill a thread. It seems that over half my posts end up being the last post in a thread. Go ahead, check out my posts. It seems completely involuntary, so I can't force a thread to end, it just happens. Maybe its just an undeveloped super hero ability.
