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.
