"Sure, its better to have more than one person in the company... and feel free to call your second thru fourth employees 'co-founders' or give them 'founders stock'... whatever."
it's alright to have co-founders as long as everyone agrees that at the end of the day one co-founder has the final say no matter what, though I don't think it's necessary to be disparaging and think of them as just "employees"...
