One of the few aggregated RSS feeds I’ve been a long-time subscriber to is Headlines from PR weblogs at Blogdigger.
This list, started by Constantin Basturea way back in 2004, is a great resource if you want to get the content from many PR bloggers from around the world - close to 500 at my last count - all in one go.
It really is international, and I noticed the other day a post in Russian from BusinessPR.ru. I wish I spoke Russian so I could understand what the content says. I tried Babelfish, but it gave me error 157 when attempting a translation. Anyway, you know what interesting translation results that tool invariably produces 
In any event, it’s terrific to have a Russian-language PR blogger in this group. Running on WordPress, too.
Incidentally, a related resource that’s also good (and also started by Constantin) is the PR blogs list on Bloglines.
