The social media player, iLike, has had a roller coaster ride in its valuation. Perhaps it has been a fun time for the customers (like me), listening and sharing their music tastes. And, perhaps it was an exciting ride for the staff, as they counted their paper money stock options.

However, for the investors (e.g., Ticketmaster), who appear to be losing at least half their value, it must have felt like tossing your lunch after the worst ride at the fair.
