>They focus on the follow-on startups and think "because so-and-so did it, I can too!" instead of actually looking at the problem and trying to understand it. They appear to be startups for startups sake.

I saw this mentality when I went to a Mountain View meetup (for a semi-related hobbyist group). One young woman there was a nurse (or related medical professional) and announced that she wanted to get involved in a startup, and could someone point her in the right direction. Immediately a group member asked her what kind of start up and she looked completely surprised by the question and said "something in medicine ... front ... end?"

I've also gone to a Startup Weekend where something like 95% of the ideas were things I had literally thought of myself already but dismissed long ago because of obvious problems, or that the proposers couldn't answer the most basic questions about. When it came time to cast our three votes, one of mine was basically to say "not really exited by this, but ahead of virtually everyone here".
