We've build this device for local businesses such as little stores, shops, bars, restaurants...etc, it seems that the average number of fans of these types of fan pages is comprised between 0 and 99 999 fans.. Plus we are sure that Facebook pages with over 100 000 fans would prefer a custom version of Fliike.

This could be solved by adding a period and "K" flaps. That way if it got bigger it could display 212.5K... not big deal for small businesses but I could see you offering that to a bigger chain of businesses.

I like that approach too, but a big part of it is seeing the numbers change in real time. Your approach would have to wait 100 like's, but I guess at that amount it still can change fairly frequently.
