What’s the easiest interface for a web app you can come up with? Some smartass out there is probably squirming in his seat right now and blurting out, “Oo, oo, a button!”

Sure you can just have a screen with a single button on it to fire off an action, but what would the point of that be? You haven’t allowed your user to specify what they want that button to do, so does it really count as an app? You could have a screen with a few buttons on it that each fire off a different action, but then you have to fuss with labels for the buttons, and think about the ordering and placement of the buttons, and does the user understand what the button labels really say…UX professionals can theorize pretty much anything into the ground.

How about a text entry box and a button? How about letting a user build a web site by means of little more than said text entry box and a button? That’s what they’re doing over at Jottit, and it’s looking pretty good.
