Thomas Gregersen of Copenhagen is running two great online sites in political theory and philosophy.
PoliticalPhilo is a primarily a Twitter service, but also exists as a website with an RSS feed, which is how I keep up with it, as I do not use Twitter. Great selection of links to books, interviews, blogs, articles, news item etc in political philosophy. Alright, it did link to my first ‘Liberal and Libertarian Foucault’, which is how I know about it, but great links in general.
Political Theory - Habermas and Rawls A blog devoted to news and items relevant, broadly defined, to those two recent giants. Not favourite thinkers of mine, but certainly thinkers who cannot be ignored and who continue to inspire important discussions. I particularly recommend a recent item, with links to articles in the German press, about a dispute in German newspapers between Peter Sloterdijk and Habermas’ student Axel Honneth, referring to Sloterdijk’s Nietzscheanism and leanings towards cutting down the state, including the social state.
