Consider adding a closing paragraph where you invite people to write in zulip to leave their feedback.
In the document you mentioned multiple times that you want the user feedback, but maybe they don't know where to send it 👍

I enjoyed reading the article, thanks for putting it together 🙌
None of my comments are blocking of course 👍

I'm not going to copy-edit this, but the content looks good, and I definitely think we should do these every couple of months. 👍

@jtgeibel looks like I need an approval from a team lead again 😉

[Turbo87]

also, all review comments should be addressed now :)

[marcoieni]

Minor complaint as a new-joiner: I would have loved to review the changes, but the force-push makes it hard 😵

[Turbo87]

fair, sorry about that 🫣

[Turbo87]

I've git refloged it and restored the intermediate commits :)

[marcoieni]

oh, wow I didn't know you could do that!
Thanks, all the changes look amazing ⭐

[Turbo87]

@rust-lang/leads I already have three team member approvals. Could one of you approve to so that we can ship this? 🙏

[Kobzol]

The date is a bit stale (26 July), let me know if you want to change it and I can re-approve.
