Unlike other social networking sites in which users maintain their own profiles, Yahoo Mash allows users to edit profiles for friends.
The concept is similar to a wiki, where any number of users can edit a single page or article. Users will have the ability to limit editing permissions, allowing only friends to make changes or revoking the ability to edit the page altogether.
Users will also have the ability to customise the page with in-house and third-party add-ons, similar to those in Facebook.
The default profile includes a 'Mash pet' application as well as a short questionnaire and video-sharing space. Yahoo hopes to include more applications as the service nears its release.
Mash had been accessible only to Yahoo employees as a closed beta service when a New York Times reporter was accidentally notified of the service on 12 September. Two days later, the invitation-only beta version was launched.
Rumours connecting Yahoo to a social networking site have been circulating for months.
Mash is Yahoo's first venture into a dedicated social networking site, but the company has several products with similar sharing and networking functions.
