There is potentially a lot of information I want to share, and it would be weird to have dozens of notes all over the house. Plus it would be fairly natural for the renters to read them and then immediately remove them, and then, weeks later, forget what they said; "Wait, what's the trick to getting the bath temperature right? Wish I hadn't removed that sticky note!"
Also, I can spend the next week+ building up the "library" of notes as I go through the house, vs. having to do it as a "last chore" before we leave the house, putting sticky notes all over the darn place and trying to prevent my 3 and 5 year old children from grabbing them.
And we could re-use the virtual notes with zero effort the next time we rent the house.
It has the following problems:
1) A bad chicken/egg critical-mass problem for adoption. (Apple, Google, and maybe Facebook are best positioned to overcome this, if they built the feature in to their OS or apps)
2) Content moderation.
3) Even if you treat it as a friends-and-family thing rather than a more broadly social experience (which solves #1 and #2 fairly well) AR on a screened device is approximately 1,000x worse to use than on the hypothetical non-dorky and practically-useful-battery-life AR glasses that every major tech company seems to expect in our nearish future (judging by their continued emphasis on AR, despite its being kind-of a shit and gimmicky interface outside some niche uses on current hardware)
I suspect 2 and 3 are why FB, Google, or Apple haven't taken on the challenge in 1, yet. I expect they will if/when 3 gets solved, and this kind of real-world commenting/tagging thing will be widespread in a hurry.
A sticky note placed on a wall with something written on it should disappear if it's painted over. How do you handle that?
What about indoors where gps may not work?
Why?
Imagine having to tap into the work history of a machine and add latest repair works and notes for others.
Don't know what you mean by Siemens, Microsoft & PTC.
One alternative is to have QR codes that point to a dataset in a database.
It makes sense as around that time Twitter was growing fast and location based services like Foursquare and Gowalla were popular. As well as Google/Niantic Ingress.
Our iteration was based on the concept of “shouts” that had a location and a visibility radius. Reshouts would increase the radius further.

Lots of indigenous cultures were/are based on memory techniques based on tying specific pieces of knowledge to exact locations: https://www.goodreads.com/book/show/29759605-the-memory-code
There used to be an app that allowed to tag and write things on wall. It's of course only visible when you are on the spo.
I am huge believer in the coming of time and location restricted layering of data/art/app.
