Weren't some of those because Adam couldn't make it?
Or do you mean your guests (David Gaulman, etc.) cancelled their appearances a few times?
Are you measuring progress by ratings? If so, what have they been lately, and what are you expecting? Did they go up after the format change a few weeks ago?
A small suggestion I have is that sometimes you cram too many topics in a 30 minute show. I would say keep it at about 4, no more than 5. Sometimes you start a topic with less than 5 mins left.
Another suggestion: Bring
Onyinye djokovic more often?
