Yeup. Lots of arm-chair advice these days. It's a business all in itself. It's funny watching people compile lists of "all the mistakes" in hopes that not repeating a single one of them will equal success. Plenty of wildly successful businesses became so without having MVPs or setting up fake landing pages. They spent years building out real product-breakthroughs, maybe with even real technology/science. I'm willing to bet that for every rule that's broken in that StartUpGrave twitter list above (I haven't looked so I don't know what's really there, but I'm going on just the idea of compiling lists of mistakes), there's a company who succeeded while still failing the rule.

There's so much retro-active quarterbacking that goes on (especially in the VC-world) that says X company was success because they applied this-thing-I'm-just-now-naming as a rule. Even though, Apple has taught us things like you're users don't always know what they want or need.

I totally agree with that! There are tons of companies that "win the lottery", and build a product with no validation and succeed. It is obviously not the "right" way to do it, but sometimes it does work.
