One word: stickers.
Scanning through my Gmail today, I noticed a bright red link at the top of the page reading, “Do more with labels!” I clicked through and landed on Google’s What’s New page, where I spied a unicorn posing in front of a rainbow.
I thought maybe they were getting on the cornify bandwagon (hat tip to Ryan), but the modest use of glitter led me to dig a little deeper and learn that Google is indeed giving away stickers for the low, low price of a self-addressed stamped envelope.
And now that Google’s released Latitude, you know exactly where you can find friends to swap stickers. Integration, people. Integration.
