well most of them are startups.
While in New York I went to some networking events where people said 'I work for a startup', 'How long have you guys been around?', '4 years', 'That doesn't really sound like a startup.', 'I know, but we FEEL like a startup.'... A*holes.
Sure, many others may be startups, perhaps even most. But since when do we generalize away ~30% of some population. That's not very scientific. I can't think of many scenario's where this would be acceptable.
It is like saying that your car or house is new after 10 years. Or saying your shoes are new when they are 6 months old.
The word is pretty self-explanatory, it is not that hard people.
