Since we ended up with 105 bingo cards last year, and several people claimed somewhere close to that number, I'm not trusting this group to exercise temperance! ;^D But I think this thread has illustrated that it's important to continue letting people play in the way most fun for them, whether drabbles or novels or photomanips ... or reviews and meta. :) I agree with your last point for sure and tend to feel that the more people welcome at the table, the more fun we'll have.
