This article doesn't give me any idea where I would start. At all.
I wish it did. I've looked around for quick and dirty ways to try to build the app I want to build. They never seem to do what I want them to do, the "in minutes" part fails to materialize for an outsider without a strong coding background, etc.
I think there are some wonderful tools out there and it's always good to lower the barrier to entry so people with other strengths can do their thing, but I read ideas like this and think of a book I saw written by a professional clothing maker who was decrying the shortcomings of off-the-rack clothes and the punchline was to the effect of "Why would you wear that dreck? Life is so much better when you can easily make custom pants in minutes -- like I can because of my many years in the industry!"
I didn't buy the book. My mom sews beautifully. I know something about making clothes and, no, you aren't going to replace off-the-rack clothes with teaching the whole world how to make custom clothes "in minutes" because that's so much better and easier.
