FB code was crap. HIs original intention was to do face recognition and relate people that didn’t know they were related; friends, etc. If you had a pick of someone and they were in another pic on someone else’s site, FB would tell you. Hence, FACEbook.
I thought his original intent was for frat boys to rate girls on their looks.
Question - is there a way for Joe Average to search for a person’s picture across the internet? Can one find the person or the same picture on different sites?
