In which year was the social networking site, Twitter, launched?

I hate all these what year questions I have a job rembering when my kids were born.

I always thought that Twitter users should have been call "Twits".

luckycatfay, Next time try this maneuver when you encounter dates, lengths, weights, distances, and the like. First eliminate the highest and lowest answers, then use the "double chance" hint to select one of the two remaining answers, if it's wrong, then use the double chance hint and select the only remaining answer.

luckycatfay, good question and answer!!!
