Taskrabbit is a cool service that helps people list local tasks that they'd like to hire people to do. It's also a great example of behavioral design-- helping users not just complete the task but want to do it as well.
Here's the new task UI:
1) Great copy is great communication
Copy is UI, UI is copy. The only way you can explain what's happening on the screen is by the text and elements on the screen. They work together. You must explain what's going on, and what's next. Yes, you know what's happening, but you're the creator of the UI. Users have no such context.
Remember that as a designer, you must design with intention in mind, but evaluate what you create with beginner's eyes. Often in YC office hours, PG will point out glaring holes in people's designs -- but it is because he has honed this skill of viewing a web page with the eyes of a novice, even if you've been talking about the idea with him for hours.
Clear your mind, read what you've got, and if it doesn't make sense, then explain. Rinse, repeat.
2) Great use of contrast to determine what's important and what's more information
You'll notice the darkest pieces of information (highest contrast) are the headers for the specific inputs. "Title of your Task" for instance. It's big, it's dark, and it commands the most initial attention. This establishes a visual hierarchy. All things below that title pertain to that particular input. There's proper padding between inputs so that the grouping is further reinforced.
Some products mistake extreme brevity for being simple. Wrong. You should strive to have enough text to properly guide the user to their task. A long block of text that is undifferentiated won't be read, of course -- so your main tool here is to make the important stuff bolder, larger, and command more attention. Then write additional text in a smaller, lower contrast font.
If they care, they'll read it. If they don't, they won't. And that's just OK. The important part is that people complete the task.
3) Show a lot of examples
It's the worst when UI doesn't show an example at all. It's the rudest experience. Imagine a brusque waiter, or a bank clerk who can't be bothered to help you with what you're trying to do. That's what you're doing when you don't show more examples.
Yes, that even means helping people with writing titles.Notice how Taskrabbit drops a greyed-out tip right there in the textbox.
DO THIS. There's nothing that will orient a user more as to what they should put than text right there inside the textbox they're about to fill out. Don't forget to clear it when the textbox gets focus, though.
4) Progressive Disclosure
See those little links at the bottom? They're optional. And they don't take more space than they need. If someone wants it, they'll click. If someone doesn't want it, they won't.
This is virtually your only tool to create things that are both powerful and simple. Use it everywhere and you too will be both easy to use and powerful.
Remember, UI is a conversation that you have with your users, hundreds if not thousands of times a day. But if you can make that conversation go well... it'll be a few million times a day soon enough.
Again, props to Sarah Harrison, @sourjayne, Taskrabbit Director of UX. I am impressed. Two thumbs up, way up.
