Even the Washington Post has blogs. That's where I saw this reference to a site that has conversations overheard on New York City streets. How bizarre is that? If you click the link, be warned! New Yorkers don't seem to have many G-rated conversations. Or even PG-13. Mostly R and NC-17.
I checked the About link and it turns out the site is a tie-in to a book of the same name. Go figure!
