What happened to Anonymous user feedback now in testing?
Now when I visit a Stack Exchange site as an anonymous user, I can't find a feedback button. Where did it go?
According to Recent feature changes to Stack Exchange the way that works was changed on 2013-02-11:
So you just press the normal up / down vote buttons to provide anonymous feedback although it now appears as follows:
The 'feedback' button shown in that post doesn't exist anymore.
The Anonymous post feedback that was collected through that button is now collected through the regular vote buttons. Logged-in users without voting privileges will see a message saying that the vote is recorded but not displayed publicly, logged-out visitors just see a message prompting them to sign up or log in...
The data is available as part of the 10k tools at /tools/post-feedback, although the link has been removed and some of the data is broken so I'm not sure if it's maintained and/or reliable.
