Wikipedia has launched a new Nearby page for the web and mobile devices that shows information about locales that are close to you. All you have to do is point your mobile phone web browser to en.m.wikipedia.org/wiki/Special:Nearby. It will then display a list of articles, near to your current location.
The image to the right shows, the articles it found in Little Bytham. While testing it with Firefox mobile on my Samsung GALAXY S3 LTE.
