With gathering of more then 250 developers this proved to be a much needed event there and congratulations to organizers for doing it. As a organizer of similar (but much smaller) PHP community in Zagreb I was in constant contact with organizers and was very happy when we were invited to join them on this occasion, especially when they approved my proposal to talk about Laravel4 there.
Even the local media picked up on the meeting and a larger venue had to be found at the last minute due to the overwhelming response. There were a few different topics mentioned (including BDD, a questionnaire, best practices in component libraries and web security) before getting to the main talk.
I would take this opportunity to thank whole PHP Srbija organization committee for inviting us & once again congratulate them on bringing such a large community together.
