Since 5/2005 I am member of xing.com (www.xing.com) formerly known as openbc. The first German business community. Many people I know from my job I am connected over Xing today. An advantage of being member of such a  B2B community is the fact that nearly every member keep the profile actual. I am still using this portal for find people who can offer me what I need for the job like products and informations. Until a couple month xing was my most important platform. This changed with being member in other social web 2.0 communities. Today most of my profiles in the net are merged over open API applications (API:application programming interface). xing doesn’t offer an open API. So my xing profile is not merged with my other profiles. I believe if xing will not offer such an API in a short time they will loose more and more share of the market.
