I still can't get a handle on the "number of OS2World viewers" ... because, if we go by thread stats, I see 10's of 1000's, upwards to a few 100k's. On recent threads ... that's a bunch, although I have no idea of their makeup.
What I think I see on this forum is these types of OS/2 users:
1. those who run OS/2 (ArcaOS) natively on old/new hardware. Problems galore (device driver, apps, no x64, no modern browser, etc.). They would benefit from the browser service, if it can be marketed to them. They may also be using RDP or other locally networked machines to get at services (at the cost of more hardware machines, more complexity).
2. those who run OS/2 (ArcaOS) in a VM (virtualbox, with their guest additions). Given a Win10/Linux host os on the hardware of one machine, you can run many OS/2 or ArcaOS vm's, and nearly all problems of this forum go away. With this thread's browser service, or with AToF (using Winflector locally, requiring only a single machine), you can pipe anything into the OS/2 vm's, so you can stay in the OS/2 VM all day, No modern browser problem.
While I don't know if VBox will be around forever, AToF lets you run the same components forever, so it's more a matter of ArcaNoae continuing to provide VBox guest additions for any future ArcaOS versions. If they do, things like this thread's browser service (or AToF) will also run forever.
But, *how folks run their copies of OS/2 (ArcaOS)* is really the key consideration. Many are still of the generation of "one machine, one OS", and if it isn't ArcaOS, or can't be programmed/built for ArcaOS, then it's time to switch. Personal choice, but ...
Solutions like this thread's browser service, or AToF, let you run OS/2, eCS, and ArcaOS nearly forever, on one machine ... and they solve all OS/2 problems ... that's not nothing! Just have to wrap your head around it.
It may not be the OS that is dying ... it may be the older type of OS/2 user (native hardware or bust). Which gets us back to finding and marketing to the newer type of (potential) OS/2 user (virtualized).
Windows is so captive/problematic that the opportunity to switch from it is there ... Linux is capitalizing on this. OS/2 (ArcaOS) can as well.
