I don't see anyone commenting on the amount of bandwidth this will free up though.
Instead of someone's RSS Client polling 30 websites every 15 minutes, you have a single 'hub' that gets pushed data once (the hub doesn't even have to poll). This is not to mention all of those blog sidebar feeds that display things like flickr/delicious/twitter/etc.
On the other hand, this might screw up 'reader statistics' depending on how it's implemented.
