Right now I have 234 feeds in my Google Reader. Many of them are updated irregularly, often weeks or months apart. But when they do update, I don't want to miss it.
If RSS is killed, what will replace it? Not for the case of Twitter or TechCrunch, where there will always be new content when you visit and it doesn't matter if you miss some, but for rare but important postings.
Me, too. And, crucially, Google Reader supports pubsubhubbub, so you get near realtime, pushed updates of arbitrary payloads. The only technology that offers this in a practical form is rss/atom.
