The new social networking site MOG launched this week with the aim of connecting people based on their taste in music.

Started by former MTV executive David Hyman, MOG requires users to download an application that catalogs the music on their computers, monitors what they play the most and what new tunes are added through downloads. The data is posted to users' public MOG Web pages.

Hyman says people want to meet others who have similar taste in music.

Ajax is a software development tool that allows users to run full-featured programs in their Web browsers. Whereas Microsoft Word is a bloated program that takes up lots of space on a hard drive, the Ajax-enabled word processing application Writely works in your browser.

Ajax is behind Google Maps and the instant messaging tool Meebo. Other Ajax applications do e-mail, calendars, and games. Ajax is attracting more software developers and venture capital.
