I’m not a connoisseur of poetry, modern or otherwise, but I do think there’s an important insight here:
Poetry has entered the same failure mode that architecture is also stuck in and that is also at the core of the many problems of the humanities. Participants in these fields aren’t being judged by outsiders (the public), but by other insiders. So they optimize for what other participants like, not for what the public likes. This is a rational result of their pursuit of economic success, since by far the most likely path to long-term financial stability in these fields is a position in academia, preferably with tenure. These positions are given out based on the assessment of their peers, so that is who they optimize their work to please. This creates a dynamic that explains everything about why poetry, architecture and the humanities are in such a terrible state these days.

Ninety percent of everything is crap. This profound scientific principle may have more empirical evidence behind it than any other supposed natural law.
In 1239 Pope Gregory IX accused Frederick II, Holy Roman Emperor and King of Sicily, Germany, Italy, and Jerusalem, of
calling Moses, Jesus Christ and Muhammad ‘charlatans’ and ‘deceivers’ who had fooled the entire world, of scoffing at the notion ‘that a virgin could give birth to the God who created nature’, and of maintaining that ‘one should accept as truth only that which is proved by force of reason’.
In reality Frederick probably wasn't quite as awesome as the pope makes him sound but the fact that the accusation could be levelled at all implies that atheists were rather thicker on the medieval ground than we often suppose today.
99% of people on the internet are lurkers, they consume but they don't produce. The overwhelming majority of the internet's content is produced by the other 1%, and those people are nuts.
Because a thick volcanic fog spilling south from a gigantic erruption in Iceland plunged the world into darkness for a year and a half, leading to a global famine. Right then, starving in darkness, it must have seemed like things couldn't get any worse, but really the famine was just a warm-up for the first ever outbreak of bubonic plague in 541 which killed half of the poor buggers who'd manged to survive the hell-fog.

Interesting interview with William Foege, one of the doctors responsible for the international vaccination programme in the 1960s and 70s that eradicated smallpox — easily the single greatest achievement in human history.
To put it in perspective, smallpox killed roughly 300 million people in the 20th century alone, most of them children. In its last hundred years it killed maybe 500 million people, about five times the total number of people killed in all wars over the same period put together.
To a first approximation, curing smallpox was equivalent to 'curing war', except five times over.

Great article by Steven Pinker. I particularly like this passage where he describes 'classic style', an aspirational ideal for academic writing:
The guiding metaphor of classic style is seeing the world. The writer can see something that the reader has not yet noticed, and he orients the reader so she can see for herself. The purpose of writing is presentation, and its motive is disinterested truth. It succeeds when it aligns language with truth, the proof of success being clarity and simplicity. The truth can be known and is not the same as the language that reveals it; prose is a window onto the world. The writer knows the truth before putting it into words; he is not using the occasion of writing to sort out what he thinks. The writer and the reader are equals: The reader can recognize the truth when she sees it, as long as she is given an unobstructed view. And the process of directing the reader’s gaze takes the form of a conversation.

Imagine we're living in an oppressive theocracy. Secretly I'm an atheist. I don't even believe our God exists, I certainly don't support any of our oppressive laws, but I don't say anything because I figure everybody else believes and if I speak up I'll be tortured and executed. Now imagine everybody else feels exactly the same way.
That's pluralistic ignorance and it's the most underrated phenomenon in social psychology. You can build empires and religions on pluralistic ignorance. (More prosaically, it explains why authoritarians viscerally dislike the idea of online anonymity.)

This blog post from back in the mists of 2012 may have the most perfect blog post title ever written. The article itself is pretty good too. The Last Psychiatrist certainly doesn't think much of academia:
Imagine a large corporate machine mobilized to get you to buy something you don't need at a tremendously inflated cost, complete with advertising, marketing, and branding that says you're not hip if you don't have one, but when you get one you discover it's of poor quality and obsolete in ten months.

Patrick Wyman had just completed his PhD thesis on the late Roman empire when he recorded this podcast series and his expertise shows. Balancing scholarly rigour with entertainment is a tough challenge but he manages it impressively well. The series has 23 episodes in total, each about 40 minutes long.
Rob Reid's After On tech podcast is a series of in-depth interviews with smart, interesting people at the top of their fields.

Bryan Caplan's thesis: college degrees are valuable but not because colleges teach important knowledge or skills — they mostly don't.
