The conference itself was excellent - I spoke about "Working with Web Services" which is basically an overview of everything you need to know to be able to consume web services. The slides for that are online at http://www.slideshare.net/lornajane/working-with-web-services.
I also saw some great talks from the other speakers there, some were people I often see at conferences, others were familiar names, and yet more were people I'd never heard of but I certainly learned a lot from all these groups. One thing that struck me was that the majority of the conference talks were in English - my experiences from looking at these events in southern Europe is that they tend to be held in the local language which of course makes them much less useful to me. This event was predominantly in English, the introduction and (most of) closing session were in English, and most of the talks were too. Whether this signifies a shift in the culture of technical events in Spain or whether this was simply a nice decision by the organisers I'm not sure.
I also made it out into the city which was beautiful. When I publicised my trips, so many people sent me information about their favourite places to go, trips to take and so on that I dubbed Barcelona "city of memories"! I didn't make it to very many of those this time around but I'll definitely return to the city in the future - its simply breathtaking.
Congratulations to the organisers - I'm looking forward to the event in 2010 ;)
