If you're a speaker (or even if you're not and just want to play with the API) and have information on Joind.in, Lorna Mitchell has a quick way you can pull you information from the site into an easy to use format.

I've recently been thinking that I should also do a better job of linking through to the various talks I'm giving/have given - and at around the same time I was contacted by the good folk at mojoLive about integrating against joind.in. To cut a long story short, the joind.in API now has the functionality for users to retrieve their list of talks!

Her example just uses a file_get_contents to pull the data from the remote URL in a JSON format. You don't need to be logged in to get to the talk information, though, so you won't need to bother with OAuth for this one. A snippet to loop through the results is also included.
