At a recent social media conference, we started talking about unique or cool Twitter sites. We weren’t talking about the ones that shared about life’s mundane events. Rather, these were ones that provided information in a unique way.

It’s amazing what can be shared in 140 characters – the maximum amount that a tweet is allowed to have.

Here are three that fascinated me:

1. @cookbook: Maureen Evans is the author of the Eat Tweet cookbook. She tweets tiny recipes that serve 3-4. At first it’s a bit daunting but with the aid of the glossary she provides, it soon becomes simple. The New York Times called tweeted recipes quite possibly the “first great recipe innovation in 200 years.”
2. @RealTimeWWII : This one features World War II tweets from 1940 and will continue for six years. Alwyn Collinson is an Oxford history graduate who tweets up to 40 times a day. He uses eyewitness accounts, photographs and video to make it feel as if you are there.
3. @TVGuide: If you’re like me, you spend a lot of time channel surfing in search of your favorite show. I use TV Guide’s official page for TV news, scoops and live event coverage.

Do you have a favorite? If so, please share it so we can all enjoy it.
