[Closed] Interesting Blogs, share your favourites

I enjoy a good science / interesting fact type blog

Here are three of my favorites

[url= https://www.damninteresting.com/ ]Damn Interesting[/url]
a mix of history and science on the whole very well written. My favourite recent topic is this [url= https://www.damninteresting.com/the-zero-armed-bandit/ ]one[/url].

[url= http://waitbutwhy.com/ ]Wait But Why[/url]
mainly science and the author's own cod philosophy complete with bad drawings. The blog doesn't seem to be updated that often but some of the topics he covers he does really well. [url= http://waitbutwhy.com/2014/05/fermi-paradox.html ]Fermi Paradox[/url] is excellent.

And of course [url= http://what-if.xkcd.com/archive/ ]What If[/url] which is simply brilliant

What interesting web-gems am I missing?
