I’ve been all over Google+ lately, and I recently finished an article How To Create Events On Google+, via Google Calendar, on that platform. At best it’s a hack until Google releases an API that can be used. Shortly after that post went up I ran across ReverbNation, which provide two very slick Facebook apps, one for bands, one for venues.
The new app, can be seen in action over on Brooklyn venue The Knitting Factory’s Page. It’s simpler than the band app, but includes a lot of features that make venue/promoter content more shareable and interactive. Best of all it’s free and looks slick.
