Query: Size does not matter -- in the virtual world. Comparing online social
  networking behaviour with business success of entrepreneurs   We explore what benefits network position in online business social networks
like LinkedIn might confer to an aspiring entrepreneur. We compare two network
attributes, size and embeddedness, and two actor attributes, location and
diversity, between virtual and real-world networks. The promise of social
networks like LinkedIn is that network friends enable easier access to critical
resources such as legal and financial services, customers, and business
partners. Our setting consists of one million public member profiles of the
German business networking site XING (a German version of LinkedIn) from which
we extracted the network structure of 15,000 start-up entrepreneurs from 12
large German universities. We find no positive effect of virtual network size
and embeddedness, and small positive effects of location and diversity.
