internet ninja
An internet-savvy person who knows about numerous websites, blogs, etc. and how to get the most out of them. Anyone can use Google to find something after enough digging; but an internet ninja knows exactly what websites to go to for immediate answers or solutions. They are swift and lethal, in and out before you even know it...with whatever they want--just like a ninja.
Can I commission the use of your internet ninja skills to help me out with this dilemma?
