Yes, there is no way to stimulate interest into OS/2, sad but true. Younger generations do not even know the system and they never tried it.
I suppose we all use and know alternative and new systems, but since we are old OS/2 users, we still have an eye of regard for it. This is not the same for youngest, most of them know only Windows, OSX, Linux and maybe Android.
Martin, about your "there is no much feedback", this is quite normal: everyone lives its times, and OS/2 users now are very few.
Patience, we will remain on amateur way.
For sure, after 30 years it is still alive/used and only this assertion say all!
