I've found a few issues when using the new article feedback tool with Screen readers:
*Due to the lack of standard radio buttons, it can be difficult (if not impossible) to figure out which option is being selected in the article feedback tool when using screen readers. This applies to all 3 options. I tried it with both JAWS 10.0 and NVDA 2011.0.1, using both Internet Explorer 8.0 and Firefox 8.0.1. Neither of these combinations were very easy to use, because of the non-standard radio buttons.
*I wasn't even aware that there was a ratings feature until I tried to view the article feedback. Could this be made accessible, by using alt text on the graphics (1 star, 2 stars ...) would do) and standard radio buttons?
*In option 1, the edit box needs a form label.
