I love finding notes littered around the environment, but it's very hard to deal with a bunch of notes related to one another lying in the same place. There's a corkboard in the community machine room, but I think you need more public corkboards in places where people are likely to communicate, like quarter streets, apartment buildings, near or in subway stations, etc. Subway stations are often filled with great notes to read, and I think a corkboard would help with that.
