Angel community was watching when Facebook platform launched and they were expecting plenty of applications to launch under Facebook umbrella rapidly and eventually some one will cash in the success in terms of user base.
I guess exactly same thing happened to Where I have been. Here is the news ( TripAdvisor buys Facebook app for $3 million). This again proves few simple things about consumer space
- User base, User base, User base
- Data is more valuable than Technology
Now the race is on and applications will be more aggressive to pan out, attract more and more people. Facebook proved its platform strength after all.
