The inability to publish ads inline RSS ultimately killed it.
If and when the news bundling model re-emerges, something like RSS will gain favor again.

i subscribe to ~20 of this subtopics and i'm sure i will never miss an article about one of that topics.
Google (partly) killed it (by pulling people into Google Reader and then killing Google Reader).
Most (all?) news sites still offer RSS feeds.
Edit: it didn't seem to work earlier, but is working now after I added the RSS subscriptions button.
Huh? There's no such inability.
And in terms of technology, there's nothing stopping you sticking an iframe or script block in your feed. It comes back to what the reader will allow. Origin really doesn't matter too much.
