Here are some clear, canonical examples that I think convey the full scope of what RSS does for us in a Web 2.0 world:
Notification: Need to inform a lot of people about changes to information? Don’t want central control? Want to enable self-service? Use RSS.
Syndication: Publishing new information regularly? Put it into an RSS feed. This flows out to the world your blog entries, news articles, podcasts, videos, job posts, weather reports, financial updates, bug reports, etc. The software you use should be able to take your information and make it into an RSS feed.
Glue: Need to connect any service to another service on the Web (or anywhere else)? Trying to mash together data? Building supply chains? There is generally no need to ever ask anyone to stand up a new web service. Pull everything you need via its RSS feed.
RSS creates the Web 2.0 information ecosystem by enabling interconnectedness, network effects, emergent behavior, and much more as well. And RSS doesn’t demand control of the other end of the conversation. This is a big enabler all by itself and is a classic Web 2.0 force. By letting consumers of RSS use any tool or service they want on their side, barriers are eliminated and connectivity is encouraged.
