The odds that users would like to see content from the default RSS feed URLs, currently http://partners.userland.com/nytRss/technology.xml, are quite low. I recommend to rather provide a Social-Office related RSS feed, that gets updated frequently - e.g. with blog posts or documentation updates. At least those that are currently configuring SO will get something out of it. Otherwise it's just random stuff that happens to be displayed there.
This is on the default Site Template "Default Social Office Site". In case there are other RSS feeds that I did not see yet, consider them included in this suggestion. Can be hosted on liferay.com, or, if it's too complicated to get a long-term stable URL there, through Feedburner or other third party services.
