Tumblr Mafia

The clunky state of blogging was driving David Karp insane. He didn’t want a platform for polished thought pieces. He wanted something faster, messier, more expressive. That frustration sparked Tumblr in 2007, a social microblogging site where users could post anything: text, photos, GIFs, rants, all without pressure to be perfect.

Tumblr quickly became a creative haven for artists, fandoms, and internet misfits, shaping everything from meme culture to brand storytelling. Its mission? To make self-expression radically simple. In an era of algorithm-choked feeds, Tumblr still feels like one of the internet’s last wild, weird, and wonderfully human spaces.

But Tumblr didn’t just reshape online expression. It became a launchpad for bold new ventures. The spirit of creativity and experimentation that defined the platform lives on through its alumni.
