yes, as soon as I change to us-english, the socialize-button next to settings appears. switching back to german makes it disappear again.
Hope you can fix this.
By the way, it would be great if you add accounts for XING
Business Network - Social Network for Business Professionals | XING and linkedin.
XING is very common, especially in German speaking countries. And both XING and Linkedin are more business-oriented than facebook.
