Every week, two or three new such single-themed pages seem to break into the Web’s consciousness. When I put out a call for such sites on Twitter, I got back a list of more than 30, including It’s Lovely! I’ll Take It! (ugly photos from real estate listings), Awkward Family Photos, Owl Tattoos, Sad Guys on Trading Floors, Cake Wrecks (snaps of misguided cakes, like these hysterectomy-celebrating, uterus-shaped ones), and Asleep on the Subway (“Because seeing people fall asleep on the subway is a universal language.”).
