There are two rss readers
1) Feeds of slashdot and 500 other urls leading to 10,000 "news" items a day.
These stories are stuff you would like to read, not that you must read. This might die as it is just overwhelming and it will be replaced with filtered/recommended content.
2) Specific feeds of items that don't come up that often or don't have that much content where every post must be read.
This will never die. This is extremely valuable. Subscribing to a blog where the author posts every six months, subscribing to information about a bill going through congress, subscribing to a feed telling you whenever someone assigns a bug to you, a feed notifying you when someone posts a FooBar up on ebay (once every 8 years). Whenever you want to get notified about something and you will read every story rss is extremely good. The alternatives are you manually checking (time waste) or email (spam heaven).
