Lanyrd is a new site for tracking conferences and events that leverages your social networking circle to discover and monitor events that your friends are attending or presenting at. Of course you can simply browse conferences by location or topic, but the twist is the social media integration. Currently based on your Twitter friend list, when you login to Lanyrd through Twitter it discovers any conferences that your friends are involved in, as shown in screen below.
In terms of using RSS, Lanyrd has, I think, a little ways to go. Each locale and topic has its own feeds that can subscribe to individually, but I don’t see a way to track what happens with an event through RSS. I would like to see that be implemented and for Lanyrd to make one, aggregated feed that sends my updates based on topics, locales and events that I’m interested in.
