There goes the neighbourhood. Now we all can be sure that we are who we think we are. Twitter will verify it. 🙂

Verified accounts on Twitter allow people to identify key individuals and organizations on Twitter as authentic, and are denoted by a blue badge icon. An account may be verified if it is determined to be of public interest. Typically this includes accounts maintained by public figures and organizations in music, TV, film, fashion, government, politics, religion, journalism, media, sports, business, and other key interest areas.
