Antanas Mockus had just resigned from the top job of Colombian National University.
I'm amused it doesn't say why. (He was going to talk on a stage; students were shouting so loud he couldn't speak; he mooned them, they shut up, he gave his talk. On national television, too.)
[Edit] It does say why, but a while into the article.
Do you mean for "unconventionally" to modify "successful"? A leader who is successful in unconventional ways, if they intended the success, might be, but I think they'd have to (warning, tvtropes link) intend to be.
Maybe people like to hear about state-level ideas more than person-level ideas. Or maybe these ideas are more specific, while the article/documentary about Dolly Freed was more of a story.
