ZDNet's Sam Diaz called RSS a "Web 1.0 tool" and voiced the opinion that "there are better ways now".Well that rather depends on whether you're relying on RSS as a major strategy for delivery. While RSS uptake is still rising among the people who read what I write online, it is rising slowly and will never be the dominant means of delivering my outputs. Personally, I'm a big RSS fan, but most of the people I talk to admit that they rarely or never read their subscriptions.
Twitter and Facebook are great for content discovery; RSS is one of a number of tools that can be used for content aggregation. Comparing them is like comparing apples to oranges.
The real question is who is RSS hurting? Nobody.
So what is the answer? Fortunately, I've figured that out :-)
Redundancy. Publish on every available channel - paper, blog, RSS, Twitter, Facebook/Friendfeed, YouTube.
This takes some effort, but not as much as generating high quality original content.
So now you know :-)
