UNDERUTILIZED COMMUNICATION CHANNEL UNTIL NOW STICKER
Get a sticker:
Whenever you see a blank space that has unrealized potential as a location for somebody to display a message, you might want to slap one of these stickers on it. When people read the message they will experience gratitude for your defense of capitalistic noise. I'll send you five stickers for $3.50 which just barely covers the postage (~$0.71), the envelope ($~0.20) and the stickers at the printing cost I pay per sticker ($0.50 each).
