Syndication
Just like RSS. Except…
The article or “post” is written (i.e., on a blog)
The blog automatically creates a “feed” and makes it available on the Web
You use a “feed reader” to subscribe to the feed
You see updated headlines to your subscribed feeds in your feed reader
Article or “post” is written Article appears in your feed reader
“Fee
d” is
avai
lable
on the
Web
You use feed reader
to subscribe to the
feed
