music’s web-breeding-grounds

Advancing Technology on the web continues to up the ante on fostering communities. Here’s a website that came to my attention. It checks in with your local music player on your computer and then “plugins send the name of every song you play to the Audioscrobbler server, which updates your musical profile with the new song. Every person with a plugin has their own page on this site which shows their listening statistics. The system automatically matches you to people with a similar music taste, and generates personalised recommendations.”
