I don’t remember who it was they were quoting yesterday morning at Sun’s Let’s Talk breakfast presentation on Cloud computing, but Facebook being defined as “Friendship as a Service” kinda made sense.
In which case LinkedIn would be “Reputation as a Service”, I guess, and as Reputation Management as a business slowly starts to take off (as a specialization of SEO), this service could well be considered “Reputation as a Service” too: SocialRecommendator.com. Give it some information like a name, company name, position,… and it generates a randomised recommendation for use in endorsements on sites like LinkedIn or Xing (refresh to get another one).
It even sort of has an API, returning plain text:
