Unfortunately training is per feed, there's a newer Premium Pro tier with global training coming out with it, but it is much more expensive [2].

I assume this is targeted at professionals that are trying to stay abreast of developments around certain topics/subjects. If you think about it through that lens it's reasonably priced, I suppose.

I also randomly hit the front page of course, otherwise I wouldn't have seen this. Maybe I should add "rss" to my regexI'd be more than happy if you give it a go and share how it seems.

We need to get back to a world where we’d have daily or weekly issues of news that we all read so that we can’t point at the same thing and say, “that’s right” or “that’s wrong”.
So you can have a different feed for Science and Technology, and one for Australia, and one for New York. By not using the front page firehose, you can keep the number of inbound articles to a more manageable level.
Though like many sites, I have no idea how you would reach the "feeds" page from the front page (I gave up and searched Google for it)
The only thing I'm not satisfied with reading news on RSS, is that news organizations push too many articles, to the point that reading the headlines alone takes quite some time. There's nearly 100 articles per day per source sometimes. Unlike a newspaper, which has a natural structure of priority and hierarchy, in an RSS reader, every head line has the same salience, and it's a pain to weed out what's important.
I kinda hope news organizations would make a separate "weekly digest feed", 30 or so articles per week.
