The coffee houses of the 21st century are no longer in physical space, but on the internet. Instead of walking into a café and randomly converse with a stranger or stand up and give a speech or tell a story, as our great grandfathers used to do, since the first wave of internet adoption in the 90s, we have typed in to mailing lists, forums, boards, instant messaging channels, talking to random people while restlessly searching for better, faster, online gathering spaces.
Though it seemed for a period Reddit/Facebook ended the constant migration, cool kids are once more on the lookout for a new coffee house as it has become clear the current platforms have many intolerable shortfallings.
