Lanyrd launched in September. I love Lanyrd. What is Lanyrd? It’s “the social conference directory.” That’s probably not enough. Lanyrd aims to help you “find great conferences to attend,” “to discover what’s hot while it’s on” and to “catch up on anything you missed.”
It’s built on top of Twitter (in so much as you need to share your Twitter details to unlock it’s true power) and it shows you what conferences the people you follow are attending, speaking at or talking about. As you may know, I speak a bit. Here’s my profile on Lanyrd.
