I see that the Dev Blog posts are already RSS Syndicated.
Is there a twitter account associated with this?
tumblr?
reddit? I think there is.
etc.
Since it's already RSS feed, to send the RSS to twitter and tumblr is a miniscule amount of work.
Another important thing to consider is to "force/beg/bribe/conjule" the various PR communities' websites to share links, to increase your search engine results, for both realitymod.com and the community websites.
PR is obviously a multinational multilingual community, it would do Wicca well to ask people from different countries to list gamer websites/blogs/facebook groups/etc that could be sent out public relations info as the mod approaches a stable intermediate release of Arma2

R and eventually BF2

R 1. (OMG PR1.0 !)... it's a big milestone, the public relations build up needs to start months in advance.
