Well, the good thing about both Crowdspottr and Fiestastic is that, unlike classic social networks (Twitter, Facebook, etc), even if only 1 user uses the service, it's already useful for him/her, as all data (events and friends) comes from Facebook.

Of course, being widely used (at least in a specific area) would bring extra benefits and more possible features, but I like that it's useful even to the very first user.

the company behind this app is actually http://www.pangalaktik.com/ which is based out of Hungary and other european countries :P

and the people behind it are from 7 countries like Russia, Estonia ... check out http://blog.campus.carnationgroup.com/ for the complete story
