Alexander Ljung is the founder of Soundcloud, a new social music network. At the moment still in a private-beta-version, the Swedish startup from Berlin-Mitte makes online co-operation possible via special commentating functions. Soundcloud allows time-dependent commentating: The commentator does not have to indicate an exact time about a place of discovery within a music track, but he can position his comment in the music track at the desired spot for commentating. For first information check out Soundcloud-Blog.

According to Ljung, he is a creative entrepreneur with a lot of passion and interest for technology, media, arts, research and travelling. As a researcher he examines trust between people and online social spaces from a sociological point of view. He is planning to publish a book about this topic. Find out more on trustmojo.com.
