Collab would be very interesting but a logistical nightmare. What if one of the pair drops out? Do you get a backup at the eleventh hour and have to figure out how to work with them? Would you be judged on your partner's work as much as your own even though you had little to do with the skill of the outcome (e.g., there are only a handful of people I would feel comfortable enough telling them to redo something that was working even if it fit with what we'd planned).
On a scale of 1 to 10, with 10 being the the most, how much of a good idea is it to generate more comments per entry by giving out prizes (to be determined) to best commenters/team supporters/cheerleaders?
Oh god no. It's like your mom bribing your cousin to ask you to the prom.
