How are anonymous users using the feedback button. What volume of users are clicking it every day? Is there anything useful we can get from their feedback?

On English Wikipedia, I looked at a 6 hour period of data. I logged about 50 clicks an hour for logged in and logged out users. From the limited test run I did before disabled by ops, there were no patterns - there were only about 10 articles with more than one click, and when looking at those pages it was not obvious what issues they were referring to (the articles were more accessible in light mode than dark mode)

What ways are there to report the number of clicks received on the report links to communities?

For anonymous users, I was going to recommend we build Grafana dashboards like so that present the top most clicked pages as it would have provided an easier path to visualizing data in Grafana. Unfortunately, ops have weighed in and asked us not to do this.

This really leaves us with two options:

1. Support and spec out work on T361214 - and wait for a solution we can use.
2. Manually get an engineer and a data engineer to generate these reports manually as needed. This would likely be 1-2 days worth of work each time we need to do it, as the data is protected by NDA so likely would require some anonymization and review process. While this is not a long term solution this could be a solution if this data is only important say for a short period. Before doing this we would need to be sure that work is worthwhile!

What ways are there to automatically post feedback received in written form on https://www.mediawiki.org/wiki/Reading/Web/Accessibility_for_reading/Reporting to the specific wiki that feedback is from?

I don't think there is a way to automate this. As somebody who was monitoring this: The feedback ranges from known issues to general feedback as well as actual issues. I would hope over time we'd see more of the latter which is the most useful.
Rather than guessing what editors want, I think we should re-pose this as a question for the community members that are showing up to these pages. The question being "What would help you here?", "Is this page helpful?"

I would recommend however that this feedback is sent to the wiki itself rather than mediawiki.org. Although some editors are showing up at www.mediawiki.org it doesn't seem like the appropriate venue. For example many editors rely on Watchlists to learn about new feedback and this is outside their project watchlist. We should reach out to the users that are using it and ask them what they want: https://xtools.wmcloud.org/articleinfo/www.mediawiki.org/Reading/Web/Accessibility_for_reading/Reporting/en.wikipedia.org

This seems like a logical next step here.

Discussed in steering with @NBaca-WMF and @JScherer-WMF - will proceed with the plan above.
