When did I become the expert?

Helping a great friend with the set up of his blog, twitter, and facebook page.  When did I become the guru.  Well, I am a teacher.  So I guess it comes naturally.  I love to share information.  Never saw myself giving step by step instructions over the phone about computer programs.  All I want to do is paint pretty pictures, man.  Maybe next book will be a ‘How To’.
