Last night I gave my talk Web Mashups with Catalyst at the Birmingham Perl Mongers technical meeting.
We also had two guest speakers - Stuart Langridge talked about the future of Python web development, and Nick Harewood demonstrated Microsoft Silverlight and Expression Blend.
It was very interesting to hear about these different approaches to web development. Of particular interest was SketchFlow - seems like a great way to prototype and get feedback on the functional parts of a design without getting tied up over the visuals.
