I disagree. You don't need any skill. Anybody can ship a crappy photo viewer in 72 hours.

But many people can't ship a quality photo viewer even in months.

What heavily distinguished Facebook from Myspace in 2006 when it became open to public was the product culture and quality. It took 3 years to build.

Although I completely understand the point of being able to make quick decisions and execute, the problem is far from solved after spending 72 hours on it. It takes at least weeks to deliver a good solution.

I'm 100% sure you've spent a lot of time with that viewer afterwards until you were confident users will have no problems using it.
