If I site I want to follow doesn't have RSS, I reach out and let the owner know I can't follow their site via RSS. A few people implemented RSS on their blogs because of it :)
Large media outfits tend to hate RSS because it puts curation in the hands of users, and that curation function is what a lot of people will pay a lot of money to influence.
Smaller media outfits like it, because they can find readers without paying money to influence the large gatekeepers.
As blogging has "matured", the big shops are feeling more confident that they can lock folks back in to their curation.
It's the upstart outlets that I notice not having RSS at all, with a twitter handle in its place. Pass for me.
Search for what you want, click "News", scroll to the bottom of the page and create an alert.
Then you can select "RSS feed" to get a custom feed for your search terms or news topic.
Though I'd very much prefer a linebreak between index listings as a bit of contextual segregation / clausterphobia breaking.
I also find search ... nonintuitive.
Though on balance, it's pretty slick.
By the original newsbeuter author, rsstail and multitail are also damned slick. I've got an rsstail script (with a lot of pretification / scrubbing of the feed streams) that runs as an xrootconsole window on my desktop, alternating amongst various feeds.
It's pretty feature rich, fast, keyboard-oriented (supporting vi movement keys), and works great in the terminal.
Another great thing about it is that it runs completely on my own machine, so I don't have to give away information about my reading preferences to any third party, as would be the case for any hosted RSS service.
I love RSS because it gives me lean, fast, ad-free, bloat-free information. I hope it never dies.
