The UK has its own Web 2.0 Conference on 11 November in Brighton, in the form of d.Construct:
"d.Construct 2005 is the UKís first grassroots Web 2.0 conference. It is an affordable, one-day event aimed at those building the latest generation of web-based applications. The event will discuss how new technology is transforming the web from a document delivery system to an application platform. Internationally renowned speakers will discuss hot-topics such as Ajax, using the power of APIís and the future of the mobile web."
Apparently tickets sold out within 30 minutes of registration! It's an interesting line-up, including representatives from Flickr, BBC Backstage, and Cory Doctorow discussing The Remix Economy. Apparently there will be podcasts of the sessions. (hat-tip Josh Porter)
Also, over in Canada Raincity Studios is running a workshop series on blogging and social networking - with the intriguing title Blogs n Dogs. It's being held at the Banff Centre, Alberta, Canada from December 4th to the 8th 2005. (thanks Will Pate for the tip)
