I disagree somewhat with your "no relevance" view.
The scenario I see is simple.
HF radio can be used by remote locations to request a page, be it for student in a school project, or general interest etc.
1) I can repeatedly send a simple unproto packet (APRS) via HF (There are a number of methods , simple AX-25 or PSKmail etc. etc. )
2) then once that message is "seen" by someone connected to a gateway..
3) it will end up being listed in the "messages" section of Outernet. and (hopefully) the outernet system can decode the request and add the page to the carousel (like the twitter request)
The same method would work on VHF/UHF via satellite too.
Yes there may be other methods of getting the request to outernet, but that is one channel that shows that hams are not irrelevant to the working system.
That is the reason I have been "beaconing" from HF for ages , but ONLY IRSS messages have been ending up in the messages list for a few Months now, which I see as a boo- boo When it was working I managed to get at least ONE message though to "OUTNET" each day, which seem like a good enough result to me from HF during the low Sunspot cycle.
Just my 2c worth
