Here is a very cool little website for you to get some quick feedback, Five Second Test. Five Second Test lets you create simple usability tests that take about five seconds for the test subject to take. Other visitors of the site, like yourself, are the test subjects.
They have three different types of tests. All of them require that you upload an image or two of your site (or whatever it is you are testing), and they do the rest. Takes about one minute to create a test, and in one minute you can easily help a few others out by taking the tests of your own. Here is the one I made for BWI: http://fivesecondtest.com/test/8521ab9
This is a great idea, and was something I wanted to do myself. I have the weekly site feedback post, but that is for just one website at a time. You can use this service to test your logo, a landing page, icons, whatever.
