I agree with Mark. Erin has a great on-air persona. Sometimes the commentators don't get enough credit for managing how difficult it can to be "on" for extended periods of time, especially as the evening wanes.
What does everyone think of continuing this "Pods of 4 Contestants" set-up? A lot of us opposed it and the disastrous tie-breakers quagmires from last season vindicated that. I preferred one night of five matches with all contestants present. The audience gets to see 10 decks, rather than four, and the constant turnover of fresh faces kept things from reaching a lull in the midpoint.
