> instragram, whatsapp, twitter, secret But those companies are very very hard to build, I thought part of what made those companies interesting was how easy they were to build. I'm not saying their success was easy but they weren't hard to create were they? Twitter was created in 3 months. Instagram was created by 2 people. Not sure about Whatsapp or Secret but neither seem much harder. Of course scaling might have been a ton of work but that came after success.
