I’m actually a lot more worried about other things rather than can an average user figure out what subscribing is for. I have no doubt they’ll figure it out. … the thing I’ll be asking in my next interview is just how manageable have they made the feeds. After getting several hundred feeds myself it just is a mess. People move URL’s all the time. What happens then?
Robert Scoble asks some good questions regarding the long term usability of RSS and suggests a number of requirements.
Some of the same questions apply when using feeds inside an enterprise. Employees don’t want to cut and paste URLs. They need a single page which lists all the internal feeds available and a simple subscribe/unsubscribe button. And they need an Intranet page (like a behind the firewall Bloglines) where all their feeds are aggregated.
