Doing something part-time does not mean that that project is a one weekend experiment. If you do something for let's say 2 years 3 hours each day, why cannot you call that thing a startup? For some of us, quitting our day job is not an option (yet). (For example no one would invest into an eastern european guy's vision about user-friendly database access, and his ability to execute on it). But it does not necessarily mean that our projects are child's toys. (Maybe some of us work on even more sophisticated stuff than startups with $40 million funding.)
