For what it's worth, I like the Daily a bit better. I liked the week-long event as well, but the Daily challenge opens it up. Suddenly, every question is worth more and you can gain or lose the lead on the strength of a single answer. That increases the excitement for me.
Since chances of me getting and maintaining a lead is very slim (I'll miss the last 4-6 questions every day no matter what), I really appreciate the excitement afforded by a daily challenge.
One of the reasons why we liked a weekly competition initially was because people could miss questions and still make a run at winning. We might go back to that format; the daily competition is a test to see if this can work as well.
I had to double check to make sure, but we've had just 1 baseball question in the past three competitions, and that came yesterday. We try to mix up the topics to make the competition challenging. But thanks for letting us know your concerns.
