Your preferences are quite welcome as well; I personally enjoy your posts and would like to encounter them on Omnilibrium. I remembered the website having had a Philosophy category, but since then apparently the categories got re-organised.
It's often difficult to draw the line between object-level and meta-level, so I don't think such a re-categorisation would be meaningful or achieve much, but if we could play around with existing categories to include political philosophy in a more general sense, over time it will probably fill up with the sort of meta-level articles and discussions that you find interesting.
In the end, users make an online community what it is, so if you'd like to see it moving in a certain direction, cast your vote through participation.
Two months ago we began testing an experimental website for Rational Discussion of Politics. Our main goal was to create a platform that would allow high quality discussion of controversial topics without resorting to any forms of censorship. The website is now ready and new members are welcome to join the discussions.
Many thanks to all the LessWrong members who have been taking part in this project.
P.S. A note to new users. A key feature of the new website is the automated recommendation system which evaluates all comments and articles based on their potential interest for each user. The recommendation system has passed the initial calibration, but its ongoing performance is sensitive to the number of user ratings per comment/article. So rating posts that you read is highly encouraged.
