Things I've enjoyed on the Internet today.

* A Seth tribute to Charles Schulz.

* The ruins of Detroit's abandoned Belle Island Zoo. Via MeFi.

* Spy Vibe, a blog devoted to the '60s spy aesthetic. Also via MeFi.

* Three Jane Austen sci-fi films are apparently in the pipeline: Pride, Prejudice, amp; Zombies; Pride & Predators; and Lost in Austen.. What can account for Austenmania?

* I can't believe putting a totally unqualified action-movie star in charge of the world's fifth largest economy has turned out so badly for California. More on this from Ezra Klein, who actually points the finger not at Arnold but at systemic gridlock, i.e., the California state constitution and deluded Orange County Republicans.

* Why we love gambling: almost winning is almost as good as actually winning, as far as our neurochemistry is concerned.

* Grade inflation is a feedback loop: students now expect a B just for showing up.

* Life as a tie-in novelist.

* Braid, Game of the Year 2008 by all accounts, is finally coming to the PC.

And speaking of deeply unserious: that Shazam! movie may not be so dead after all.

Happy birthday, Superman! It's been 70 years since the Man of Steel appeared in Action Comics #1. io9 celebrates.
