According to the official Twitter blog –
"Today we’re launching the first in a series of Twitter stories. Read about a single Tweet that helped save a bookstore from going out of business; an athlete who took a hundred of his followers out to a crab dinner; and, Japanese fishermen who use Twitter to sell their catch before returning to shore. Each story reminds us of the humanity behind Tweets that make the world smaller. "
If you have a story than you can submit by mentioning @twitterstories or by using the hashtag#twitterstories. Include a link to a photo or video that helps illustrate your story to the world.
