mike hall is the main host of "skeptics with a k", doing each episode's intro and pre-recorded outro and editing the podcast's episodes that are recorded on monday until publishing them on thursday. he and michael marshall, on air steadily referred to as "marsh", have been present at every episode (except for a few compiled episodes hosted by mike alone) since its inception. colin harris completed the trio with his trademark goodbye "it's been wonderful", but was occasionally absent (for example, at the qed live recordings), and after a period of infrequent stand-ins by others, he decided to quit the show in march 2014 just before the birth of his first child, to dedicate time to his family. he was replaced by mss secretary alice howarth, who was featured on "swak" since april 2014.
