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.
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.
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.
