Belgium is doing great on Facebook

According to a blogpost on O'reilly, Belgium is on place 5 in Europe, with around 2 200 000 (almost 20% of the Belgian population) active Facebook users. There are a few reasons why Belgium as a small country is ranking so high. I'm thinking of a few :

• As Belgians we don't mind our site being in English. I know currently you can get FB in Dutch, but a lot of Belgians started using FB in English.
• We, Belgians, are internationally focused.
• We didn't really had a locally focused social network, which was targetted towards an elder crowd (18+). We do have Netlog, which still is (and will probably remain) really popular, but it is focused more towards a younger crowd. 
• We have a relatively good penetration of broadband connections, which makes it easy to share and browse photos/movies/ ...
• Facebook came to Belgium just when a lot of Belgian internet users were discovering that the internet was more than the basic usage like email, surfing, google, e-banking, ... 
• Facebook became very popular as a social network for students and has grown exponentially from that audience.

Others reasons? (feel free to add some in the comments)
