XTech, at its birth, was a conference about XML. Although, as I understand it, the focus of the conference has shifted somewhat in recent years to embrace other web technologies and the crazy/sexy world of Web 2.0. Shifts in focus notwithstanding, I still had the pleasure of meeting and conversing with delegates from a variety of interest areas that I hadn't had the chance to at previous conferences, from people who make dictionaries to government representatives.
My friend and fellow Brightoner Simon Willison of Django/OpenID fame has just released a lovely little mashup called wikinear that uses FireEagle and Wikipedia to show you Wikipedia articles that are relevant to your current location.
Now that I'm back from SWSX, somewhat over my jetlag, and BarcampBrighton2 is over, I'm looking forward to a few weeks of productive work in Brighton.
