User Interface Showdown

[Niheel]

To juice things up, we are going to have a best user interface contest. All you have to do is nominate a web based software or service that you believe has the best user interface.

You have to explain what you like about it and what you think could be changed.

I nominate: 37Singals

Pros:
Their complete line of products are very user focused. Simple to use and straight to the point. I like that, there is not a lot of guess work involved.

Cons:
I wish some of their free apps had some more features.

Who do you nominate?

I would say flickr.

I think the design team on that site did an excellent job. I like the color scheme and the layouts of the various pages. They use text colors that stand out, the links are normal blue or blue underline, the usability is rock solid on it. I think it's one of the reasons the site is so successful. A lot of thought went into how people would use the site.

I don't have any dislikes about the site.
