What is an unconference? An unconference is a conference where what happens is organised by the delegates on the day. The event organisers have to arrange something, the main one being a venue, but the rest is down to the delegates. So all the hassle of talk submissions, review and scheduling is taken away.
There are lots of reasons to attend the FLOSS UK Unconference 2012, including:
Keep abreast with new/emerging technologies
Network with some of the people who are responsible for developing critical applications
Become part of the UK Open Source community - build up informal relationships that can be invaluable in problem solving
Benefit from the experience of delegates with similar interests
