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.)
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.
