As you know, I work at Groovr. Well last night we launched the new version of the site. This includes a complete rewrite of the software that powers the site and a brand spankin' new design. The site still runs on Python + Django and was given lots more functionality. The real killer part is the iPhone app! Just head to www.groovr.com on your iPhone and you will be automatically placed in the iPhone app. Oh and we aren't done. We still have a list of features that will be slowly rolled out into the wild. You should definitely check it out!
There have been a few articles written about the new site already. Read these too!
