That link goes to a to a forum, which doesn't have subscriptions. I figured out the answer, though.

1. I went to the Steam Frame page.
2. Near the bottom was "Follow Steam Hardware for updates, news, and launch information".
3. That page has a "Links" menu with an RSS link.

Note: if you go to the page in step 2 yourself, the RSS link will likely be in your local language. My link above is in English.

RSS really is the most elegant, easiest, most customizable way to do this. Valve really is the GOAT when it comes to actually treating customers well (and don‘t think of them as dumb).

Never would have guessed this. Common Valve W.

Well, that's a good idea. I haven't thought about RSS in ages. Like I forgot that was even a thing. I could write a back-end that polls the RSS feed for its last updated date, and if I find something, then notify subscibers. Subscribers like an app someone makes.

I don't know much about writing Android apps, but I feel like if I were to write the stupidest one, post it on GitHub, and advertise the project to people, someone will be so offended at its stupidity that they'll fix it for me.

I can handle the back-end stuff just fine.

Just kidding. I'll go find some RSS app that has notifications. I just like making things, and making a "Steam Hardware Alert" app seems like fun.

We agree! That's what I meant when I said, "Any real news from Valve."

I guess "real news from Valve" wasn't clear enough and could be mistaken for also including NewRandomYouTubeGamerX64_L33tSauce's pricing opinions. I guess I just don't condider that news. I thought the title was clear. TIL!

I'd like to subscribe to NewRandomYouTubeGamerX64_L33tSauce's intriguing publications and productions, might I ask for a link, dear sir?

Could probably be done with email as well
