Imagine if we did a big topic in person? It wouldn't happen for me; in person, I would just sit there and quietly take in everyone else's opinion. If asked, I'd give my exact opinion, regardless of how contrary it might be. When pressed for reasons why I felt a particular way, I'd just say I didn't care to defend my thoughts. It makes for quite awkward conversation!

Ken says I should do Toastmasters (tm) in order to be better prepared to compose my thoughts in a live forum sort of atmosphere. I guess.
