Depends on what you are after.

Very few scientists are rich, and very few businessmen are good at science.

But if the goal is to make money I would pick good execution over a good idea any day. Just look at myspace ;-)

Good execution is important, but only after you have sufficient evidence from a prototype with users that it's worth doing.

Myspace had a very good idea. This is obvious because it had a million copycat sites that were pure knockoffs but still became incredibly rich.

Well tripod did more or less the same 5 years earlier, and had a million copycat sites. What exactly was the great idea that myspace had?

If you read up on myspace history and how they came to dominate the market it is quite obvious that it was by pushing their product relentlessly - not by innovating or having excellent ideas.

Its a good idea because with most other ideas you would have to work much harder to reach the same level of success.

Well that's the most cunning and insightful comment I have read in quite a while.

"because if they had done something else they would have to work harder..."

I give up. I concede. I appraise your superior intellect. I will never be able to give a due answer to that amazing argument.

fucking think.
