Pshaw to me for failing to lie about my age.
Got an invite 30 minutes after Google featured the share button (via Lifehacker), but alas, "you are not old enough to use this feature."
Facebook sucks very hard things now. It's buggy, slow, and boring -- not to mention privacy exploits.
Can't wait for the 31st (or before then, depending of Googie Bears' motives)!
