These were popular at my workplace maybe seven years ago, and while I was into the idea at first, IMO it was impractical most of the time. Turns out it's a pretty unreasonable burden to place on people that they should read and follow instructions in a document in order to communicate with someone and to personalize their work approach for every person they interact with.

I find that I never know what to write about myself in these. I had to make one for work also a few years ago for similar reasons to you. But when I would read it I could see it represented a part of me, but it's hard to say "talk to me like this" because it depends on what the subject is and who the person is. I found it was interesting to do as a team building exercise because we all did them together and read them to each other as teams but I never found myself or others getting back to it. And at some point I would've preferred if the document disappeared because years later some new joiners would read it and think something I wrote in 15mins in a workshop 6 years ago still represented who I was at the present time.
