unappreciated things that ca n't speak for themselves, like the San Francisco fog that brings a chill to summers in that city. I love everything about the fog, said the man who created @KarlTheFog in August 2010. I think the way it sneaks over the hills is beautiful, mysterious and even a little romantic. I love how it stops at certain points above the city, creating a wall of clouds. And having moved here from a city where it was 100-plus degrees in the summer, I was mostly excited to not be dripping in sweat for three consecutive months. The man, who also requested anonymity, was inspired by @BPGlobalPR, a popular parody response to the BP oil spill in the Gulf of Mexico. Through the lens of Karl the Fog, he reports on the public's feelings toward the fog and acts like a PR rep for the maligned form of weather -- with a witty bent. Karl already has more than 5,000 followers. Giving Karl an identity has brought out emphatic and sometimes cursory responses -- especially when the fog blocked Fourth of July fireworks -- but the Twitterverse has been receptive overall, he said. -LSB- I get -RSB- lots of weather puns and haikus. My favorite tweets are when people take pictures of Karl and post them on Twitter or Instagram, the man said. Seeing so many people pick up on it and tag Karl in their pictures has been overwhelmingly cool. The Orange Cone Like Karl the Fog,
