At today's Internet Briefing Developer Summit IĀ gave a presentation about writing “Twitter applications and more”. It has some slides about twichteln.ch and some about my real time web talk from earlier. It doesn't have much code, it's more from a conceptual point of view.
As always available at slides.liip.ch or the PDFĀ link above.
This also reminded me, that I wanted to blog about my little lx_notifier class, which pushes to different services in parallel. Will do, will do :)
