Hi Quim,
I am interested to be a part of this event.
This event seems to be a really nice opportunity to showcase the recently built REST API (rest.wikimedia.org). I was thinking something like a introductory session on the REST API, but it depends on the kind of audience we are targeting on because the API docs are self explanatory and are well received so far.
Let me know if you have something specific in your minds? and what kind of audience are we targeting on?
