In a previous post, I wrote that Bill Gates has left Facebook because he was overwhelmed with is "friend" requests through Facebook. Mr. Gates has now resurfaced at LinkedIn. His profile: http://www.linkedin.com/in/billgates.
Given that Mr. Gates has only three connections, he clearly is not using LinkedIn. He did post a question in the LinkedIn Answers section: How can we do more to encourage young people to pursue careers in science and technology?
As I am writing this, the question has been up for 42 minutes and there are already 32 answers posted. Mr. Gates certainly attracts attention.
The cynics among you have probably noticed the new wealth of Microsoft advertising now showing up in LinkedIn.
