The 2015 edition will be the 7th!
So save the dates: 23rd to 25th of April 2015 (the Saturday is usually a networking activity of some kind)
I’ve attended, spoken and moderated at the last couple of editions and it’s good fun. Unlike a lot of conferences there’s a manageable number of people in a venue that is much more “human sized” than some of the massive sprawling venues you end up in stateside.
Speakers and attendees are generally more European focussed, but there’s usually a few non-Europeans in attendance.
