At Awesome People Hanging Out Together, the awesome people in question are interesting individuals who are even more interesting in groups. Louis Armstrong and Niels Bohr, for instance. And Carl Sandburg and Marilyn Monroe. And Neil Armstrong, Neil Gaiman and Neal Stephenson. This Tumblr blog doesn’t explain how any of the folks came to hang out together; all you get is the photographic proof. But that’s part of its charm: it’s fun to wonder about the circumstances of the encounters, whether they happened recently or decades ago.
