"Why do this? To simply make a website or hack together an MVP (until you find a technical co-founder), you can tailor your learning to a particular project. The reality is that you don’t need to be a computer scientist for that stuff; using the “foreign language” metaphor, it’s like working your way through a country with a phrasebook."

That's a very good advice for non technical founders. Even though I'm a programmer I always do this if I have a task to be done in a language that i am not familiar with. Just learn what needs to be done... do it and move on...
