There is some great insight and advice from Paul Graham, in his interview with Issie Lapowsky for Inc. Magazine:
It’s OK to start out with a small idea. […] If you try to do some big thing, you don’t just need it to be big; you need it to be good. And it’s really hard to do big and good simultaneously. So, what that means is you can either do something small and good and then gradually make it bigger, or do something big and bad and gradually make it better. And you know what? Empirically, starting big just does not work. That’s the way the government does things. They do something really big that’s really bad, and they think, Well, we’ll make it better, and then it never gets better.
I couldn’t agree more — shipping big and good simultaneously is hard.
One of the chapters in my book, Delight is in the Details, talks about this very topic. Saying that if you’re short on time and/or energy then it’s better to postpone or abandon certain features than it is to take shortcuts on the editing and polishing of the product.
People will always be more forgiving and interested in a product that’s delightful yet small in features than one that’s feature-rich but stinks to high heaven.
