> RSS is great but it has one great flaw in that it doesn't scale that well by itself. If 2 million people subscribe to your feed and try to update it once an hour, that is 48 million requests a day just for RSS. Who's updating their RSS feeds once an hour 24 hours a day? Anyway, a very popular site with that many millions of visitors already has to handle extreme traffic, regardless of RSS.
“Who's updating their RSS feeds once an hour 24 hours a day?” RSS is a pull-type system, no?. So the end-user is causing the overload problem by hitting the publisher’s RSS feed every hour? The problem is out of the hands of the publisher…
Yes.
The web in general is also a pull-type system.
> So the end-user is causing the overload problem by hitting the publisher’s RSS feed every hour?
There is no overload problem.
And again, this math is off, because an end user is not even awake 24 hours a day: "If 2 million people subscribe to your feed and try to update it once an hour, that is 48 million requests a day just for RSS."
