Timo Haapala, 55, is a veteran political journalist. He has reported on politics and provided analysis and commentary for over two decades in Finnish media both on television and in newspapers. Yesterday, he tweeted about noticing to his surprise that "anyone" can edit Wikipedia pages. He wondered if there was anybody overseeing what is written on Wikipedia. Here's a link to the tweet.

What I find amusing here apart from the fact that not knowing Wikipedia is permissionless and decentralized is a huge gap in anyone's general knowledge is his implicit trust in third parties.
