Mitchell John Halley, known online as jan Misali (/jɒn misəli/) or HBMmaster, is an American YouTuber and video essayist. He[a] is known for creating video essays on a variety of subjects, including linguistics, mathematics, and video games. He also creates music, some being his own original compositions and some being parodies, mashups, or remixes.

YouTube career

[edit]

The username "jan Misali" comes from a translation of Halley's name into Toki Pona, jan meaning 'person' and Misali being a respelling of 'Mitch Halley' using the phonotactics of the language. The capitalization is intentional, as in Toki Pona the first word in a sentence is not capitalized by default, while proper nouns are.

Halley's first YouTube video was uploaded on June 28, 2011.

He gained a niche following from his series Conlang Critic, in which he discussed constructed languages. Some of the conlangs covered in the series are Lojban, aUI, Ithkuil, Esperanto, and Toki Pona.

The channel saw a significant increase in viewership following the April 23, 2020, release of the video "hangman is a weird game", a video essay about the game hangman.

Personal life

[edit]

Halley is non-binary and uses he/they pronouns, and is aromantic and asexual. He is autistic.[2]
