SpeedDate Pulls A Fast One. Buys HappyAppy

500,000 users of HappyApp apps on Facebook are confused after 3 of their applications overnight turned into a SpeedDate app.
Have you ever?, Romantic Gifts and Would You Rather? are the three applications that have been switched over to the SpeedDate app without notice.
There is heavy speculation that SpeedDate used some of the $6m it raised by Menlo Ventures last month to make this happen.
SpeedDate, just as it sounds, is a speed dating web site that send users on 3 minute online dates via webcam.

What will be the retention rate of these app users since their original concept had nothing to do with Speed Dating?
