Dozen new links daily, 99% of them submitted by the same person, 99% of them having zero comments... what exactly was the point? Why don't you start a blog instead? Or a Twitter account?
(Note: The last suggestion was serious. Twitter is exactly for this: many links from the same person, without discussion.)
They're trying to seed the subreddit. If there's no content, no one will be interested, and if there's no one subscribed there'll be no content... this technique is a common way to kick start the community.
(It might be worth posting fewer links though, otherwise any discussion that does happen will get lost quickly.)
I'm experimenting with a new rationalist subreddit on reddit.com
/r/rationalisthmus
Starting with links populated from the planet rationalist data set - to which I've added about 50 new sources in the past few weeks.
