iLike is selling songs and albums. That's a fine business model... But the apps like the one mentioned in the post.... He could potentially sell targeted travel related advertising, but CTR on travel ads are woefully low unless you are really close to the deal (i.e. someone is searching for "tickets from Seattle to London"). 99% of travel traffic are people who window shopping. And, of course, if places like iLike REALLY take off, why wouldn't Facebook behave like Microsoft and just build the functionality into the platform? I remember when Netscape Navigator had tremendous market share...
