The Twitterverse is expanding.

Twitter, that microblogging tool that caught on with teens and twentysomethings using it to tell loyal followers what they're doing at any given time — in 140 characters or less — is now becoming part of the business strategy for a wide range of brands, from Skittles to Fairfax County. …

Shashi Bellamkonda, Network Solutions' social media swami (yes, that's his real title), organized the tutorial, attended by about 30 people.
