Honestly, I rarely look at it, so I am not sure if they did recently update the form or not. But the thread seems like they did and they like it. One person said:
The new feedback link is much more interactive and easier to use. You no longer have to browse through tons of different options in order to find the correct form.
I think Google might be getting a little more serious about using user feedback in its rankings, but perhaps that might be going a little far in terms of assumptions.
I am not sure if I am seeing the new feedback form or not, this is what I see.
Maybe Google is testing a new form I do not see?
