Mashup postmortem

I don't think anyone noticed, but I didn't publish a "Monday Mashup" last week or today in favor of exploring the "Comic Book Improv" concept instead. So I'd like to take this chance to get your thoughts on the whole Mashup experiment. Was it good, bad, or indifferent? Would you like to see it return, or stay blissfully dead? If you want it to come back, what did you like or dislike about it?
