RSS feed on page difference

[UJK]

Is it possible to get a rss feed about page changes, I want to see all
changes about pages if anyone modify the page. Also I want to see
newly posted comments, is it possible?

There is the twitter rss if you want to see page changes,
here:

and also the twitter feed itself here:

Not sure if you can see the comments though.
