It looks as if Rahul from Devil's Workshop has come up with a "one click" RSS feed hack that will enable users to view community forums and scrapbooks through their favorite feed reader.
This hacks seems to be much easier to use than Orkut Feed (see review) although you will need Firefox and GreaseMonkey in order to make the most out of this hack.
(UserScripts.org) Insert Relevant RSS feeds on pages with ready to subscribe button
This GreaseMonkey Script for Orkut adds a link to RSS feed of current users scrapbook or community posts in top header menu of Orkut!
Also for advance firefox users, the RSS Link will be integrated into orkut so that you can get RSS indicator in navigation/address bar.
whenever you will click on above links you will be redirected to relevant RSS fee, which you can add to a RSS Reader like Google Reader.
For those of you looking for screen shots, Rahul provides the goodies over here. Users can install the script over here by clicking on this link:
Note: I will add this underneath Orkut User Tools underneath the GreaseMonkey section.
