I'm not going to use Wordpress. I'm honestly tired of Wordpress.
I don't really want to be troubleshooting (or writing extensions for) 20 year old PHP legacy code. I'd like to play with something which uses a more modern stack than that.
Even for something hosted, after the parent company bought Tumblr for a low price, they've been doing a poor job of moderation, still being censorious. Plus, I'd like to play with something more modern and fresh, it doesn't have to be something hot off the press, but not the same thing from twenty years ago.
