Good work Derek(s)! Love the collaboration and the fact that flu carnival still lives sort of! I think @phillyhistory is right that it could seem confrontational (similar to petition folks or frat boys collecting coins for the children's hospital). The key would to not harangue passers-by and put it in a place where at least some percentage (50%?30%?) of folks aren't rushing to a subway or something. You pose very good questions!
