Some feedback:

- when I tried to contribute, it asked me to login, but provided no links to login. Throw the twitter and google oauth links in that modal so I don't have to go hunting for it.

- provide a field for a url to the actual item in addition to the title, description, and image. I was trying to find some of the iPad apps that were recommended in a list, but had to hunt them down manually using google.

- on the list builder, I'd like to see some automatic link crawling so I don't have to hunt down the image and description. So if I paste in a link to an iphone app, it will crawl that site for an image, and use the meta description and page title (editable by me after the fact, of course).

- tried to create a test list, but it threw back validation errors. problem is, it didn't say what was wrong with the form.

- the tag field is not intuitive. I understand what you're trying to do, but I think saying "enter tags separated by spaces" would be more straightforward.

- A list building bookmarklet or chrome plugin would be awesome too.
