That's a great link that describes the common problems of having multiple founders! If your technical "circle" already includes people that you want to be co-founders with and you guys agree to start something because the chances look good, then this is a powerful situation to start from -- better than being a single founder. But if you don't have that "social infrastructure" established (and you have not been hanging out with that type of crowd), then just adding a co-founder may cause more problems than helping.
