I'd just like to quickly point out that the pie charts for "What gets talked about on the inside" are somewhat useless because they not only don't add up to 100%, but the sum of percentages for the facebook charts doesn't equal the sums of the corresponding google chart (e.g. cons: sum of facebook percentages: 26%, google: 22%)

I agree it's pretty stupid - my best guess is that it could be % of total respondants, not % of total respondants that selected cons. Said another way - 74% of Facebookers didn't list any cons, 78% of Googlers didn't list any cons.

Good catch!

I'm not trying to make excuses for them, but maybe they just forgot to add a wedge for "other".
