Blogging about a little app he created to demonstrate the Twitter API, developer Brent Simmons had this to say:

Folks who aren’t developers sometimes think that apps like Twitterrific are 90% under-the-hood plumbing and a 10% sprinkling of user interface. The truth is more likely the opposite: 10% plumbing, 90% user interface.

And it struck me that his comment could have just as easily been made about the medium ideapark works in. Ninety percent user interface (design, function, message, strategy) and ten percent plumbing.
