"Users demand delightful experiences (see: Pinterest, Square, Path), but at what point does polish get in the way of finding product market fit?"

I believe you should almost always distill your idea into the smallest chunk possible that still contains the core of the idea and ship it.

John's comments in this branch I think are spot on: You don't know how your users will use your idea until they use it, so don't spent a ton of time polishing things because there's a good chance that things will change drastically and you will have wasted a bunch of time on polish.

Re: Shipping without discovery:

Discovery is only interesting when you have a lot of content to discover. We don't have that and won't for a while after launch, so this is not a very important thing to have right at this moment.

Our users will see the product as it is, but we are always having to switch back and forth between how it is and how it will be. This is a hard thing to do and I think is one of the harder things to learn when building web products.
