How do you plan to get this feedback?

Actually, how did you get to these questions? What is the goal of this consultation?

@Trizek-WMF has set up translatable questionnaire using some nice tricks here:
https://meta.wikimedia.org/wiki/Tech/News/Reader_feedback/2017

The questions are chosen because they largely respond to the three areas one thinks most about when writing the newsletter (the right things? With the right level of detail? Easy enough to read?) and a fourth open question if there's something else. I have pinged Edward to get his opinion before we give the readers these questions.

Does this need to be immediate, or can it be part of the next Insights (assuming it goes out in a few months again)?

TN was included in the previous Insights but it wasn't focusing that much on content; it was more about TN's reputation. Plus this is directly dedicated to (and targeting) TN audiences.

As Benoît says: it doesn't have to be immediate, but it shouldn't be part of Insights, so no reason to wait.

Questions have been edited based on feedback from @egalvezwmf

CE Insights is good for questions to be asked repeatedly, in order to check trends over time. From the four questions proposed, maybe the first one could be a CE Insights question. 2nd and 3rd less so. The 4th would not really fit there.
