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

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.
Any recommendations on rss readers? Do I "need" to self host an aggregator or is that just if I want it cross device? Have yet to use rss and these questions were surprisingly difficult to find with a search
I just installed Read You from F-Droid.
I think self-hosting an aggregator lets you keep a cross-platform record of what you've read and what not. You mostly just need an app.
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.
Never would have guessed this. Common Valve W.
I kinda want the opposite. I want official alerts only. NewRandomYouTubeGamerX64_L33tSauce's opinion on "What a good price for the Steam Machine would be, and 10 reasons it won't be that price" really doesn't interest me. Has Valve said anything new? No? Then kindly STFU.
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?
Camp outside their headquarters in Bellevue? /s
Maybe a simple program that grabs an RSS feed from steam and searches the title for key words.
If keywords are found it passes the notification to you. Otherwise, ignores it.
Could probably be done with email as well
google alerts? is that still a thing?
