I can't honestly think of a thread that hasn't got derailed and turned into a completely different topic all together.
It's great!
I think it's because the threads in here move so quickly. Someone will say anything of interest, another will ask about it. All of a sudden, you have 2 conversations going because of natural conversational means.
now, someone will quote this ... then start 2 topics in one
1) HAN Chat
2) why threads go OT in OT.
