"Hi everyone, I'm Dr. Weselcouch! I teach math in Virginia. On this channel we drink coffee and solve math problems. We also dabble in Minecraft" Two spaces after a period and a YouTube channel with a few dozens of views per video. The co-author is his wife. "Mathematics Magazine intended audience is teachers of collegiate mathematics, especially at the junior/senior level, and their students." I wish them the best. And I'm glad everyone got another sentence on their CV. But wow.
