The site seems to encourage questions with simple yes/no answers, and to solicit sentence- or paragraph-length blurbs from commenters. Furthermore, since comments aren't obviously linked to the opposing statements that evoked them, it's hard to get a sense of dialog (as opposed to a bunch of people stating their opinions in a void). How likely is a meaningful, balanced exchange of views to proceed from that?
Indeed, I already see some signs of behavior that could lead to flame wars. One question begins, "Seatbelt fines are a joke...", which hardly seems likely to create an atmosphere of balanced, thoughtful comments. One comment on whether parents should be allowed to drug children on long flights advocates making it mandatory. Another question seems to be predicated on a news story (should a family get $200k?), but the context of the question is completely missing.
