the funny thing is how everyone goes after local with mobile and pretty much doesn't get much explosive success (sorry Foursquare but it's true). in fact, i was reading this founder's post on why you shouldn't do local: http://www.crashdev.com/2012/01/top-three-reasons-not-to-do-...

But the problem with that post is found in PG's black swan article... that blockbuster ideas and businesses that solve real problems often aren't attacking an industry directly but arise in completely different or adjacent spaces

It's another take on what "bad ideas" might actually mean... in other words, that an idea is a bad idea for what seems direct but it turns out to be a great idea because it surfaces a real problem that it does solve somehow
