gwern posts on google+ and Kaj Sotala posts interesting stuff on Facebook. I also subscribe to a number of journal's table of contents via this site to keep up with research and some stuff on arxiv.

After discussing diffusion of interesting news at the most recent London meetup, I was planning on asking something like this myself.

Futility Closet is nothing but "interesting stuff". It describes itself as "a collection of entertaining curiosities in history, literature, language, art, philosophy, and mathematics, designed to help you waste time as enjoyably as possible". It has more chess than I personally care for, but is updated with what I find to be novel content three times a day.

Conscious Entities is a blog on Philosophy of Mind. It takes an open position on a lot of questions we would consider to be settled on LessWrong, but I think it has value in a steel-manning / why-do-people-believe-this capacity.

(The categories on my feed reader are "Blogs", "CS", "Dance", "Econ", "Esoterica", "Maths/Stats", "Philosophy", "Science" and "Webcomics". I'd be interested in finding out how other people classify theirs.)

There are some blogs mentioned on the wiki.

I don't really read many blogs frequently. The one sort-of-bloggish site I visit daily is 3 Quarks Daily. They link to a number of interesting articles every day, and their taste in topics coincides quite nicely with mine.

Mr.Money Mustache on personal finance.

In the Pipeline is a very good blog to keep up with what's happen in big pharma and chemistry in general. It written by someone employed inside a pharma company, and not someone who criticizes pharma policy from a outsider standpoint. There are some posts about specific chemical reactions that I skip but if you want to understand how the healthcare industry works, I can recommend the blog very much. It also provides good coverage if a new relevant biomedical finding comes in the news. The comment section is usually full of people with domain experience.

I used to read Matt Talibies Rolling Stones blog column for Finanical news. Stories about Libor are explained in detail on that blog.

Matt now left the Rolling Stones and will lead his own magazine under the heading of First Look Media which is funded by the tech billionaire of ebay cofounder Pierre Morad Omidyar. At the moment First Look Media already publishes Glenn Greenwald & company which the primary job of still processing the pile of Snowden documents.

I used to read Glenn Greenwald for a long time but reading every other day about the NSA, used to become boring so I won't read everything that comes out in the Intercept but I subscribe to the feed.

As a German speaking independent news sources I read hintergrund, fefe and the indepth podcast Alternativlos.

Alternativlos is an interesting project. Two members of the Chaos Computer Club basically concluded that speaking to the public and explaining them how things work politically is "without alternative" and started to explain topics in 2 hours. It explains a topic like stuxnet in detail in a detail that explains what exploits cost on the black market.

Today some public radio stations rebroadcast the podcast.
