The Friday stream is not really for QA. It's more of a marketing event where Cordovan and occasionally guests talk about things to come while Cordo plays with invited players. If there are guests there generally is not play involved.
The person you want to ask questions of is Tonquin when they are on.
Nothing else that comes out of those streams in terms of bug talk is particularly reliable because Cordo doesn't ask for questions in advance and so cannot prepare answers. On a hot topic bug there will be some preparation but for the most part fixes are already in progress and Cordo is just holding down the fort until they arrive.
