At it's core, a search engine is high tech while a social networking website is low tech. Before you want to argue, I know Facebook is nowadays damn high tech but that's not the point. Techies will always have more respect for a business built on actual high tech. See Apple. See Tesla. I happen to respect Zuck a lot for his amazing ability to grow the company and maintain control rather than his tech prowess, which is nothing to be ashamed of.
