RSS stands for Really Simple Syndication and it’s a way for people to subscribe to updates to your blog using a client likeGoogle Reader orBloglines. You may not know what RSS is but chances are people are using it to read your blog. We track over 50,000,000 posts read via RSS every week. (Around a 18% addition to our on-site views!)
Why is this important? Right now how most people interact with feeds is by checking that it updated every now and then, usually about once an hour. Can you imagine waiting an hour to get your emails? (The world would probably be more productive.) RSS Cloud is an extra element in your RSS feed that allows subscribers to say “Hey, let me knowas soon as you’ve updated, kthx.”
WordPress.com has always supportedupdate pings through Ping-o-Matic so folks like Google Reader can get your posts as soon as they’re posted, but getting every ping in the world is a lot of work so not that many people subscribe to Ping-o-Matic. RSS Cloud effectively allows any client to register to get pings for only the stuff they’re interested in.
