Tumblr was very close to the perfect social media network. It's a shame it succumbed to corporate greed after the Yahoo acquisition. I really hope someone manages to recreate it as a decentralized protocol
The problem is about their content censoring. I don't reckon Automattic reversed the "sexually explicit" purge initiated by Yahoo. I'm not interested in a social network that censors ~30% [1] of the global art production. For now Twitter is the better place for relatively free content sharing.
[1]: Number pulled out of my hat, but the human nude being the most popular drawing subject ever, I wouldn't be surprised if this is close to reality.
