Avoiding the whole 'ettiquite demands you stay in an akward conversation' stuff is one of the reasons I like these discussions. Plus I [introvert] have more time to formulate replies.

I'll still try to 'read the room' a bit, and either stick to conversations or acknowledge that I'm asking something out to left field.

And yeah, my brain accumulates a lot of really oddball ideas, musings and wonderings. (Digging through my brain can be like beachcombing after a storm.)
