Well, I finished authoring my first SVG tutorial today called "SVG Kickstart". You can read it here. It's 5 fairly short pages, but hopefully it gives a good justification for the practical need for SVG on the web today. Future tutorials will likely delve into the more "flashy" effects one can get from SVG...
I love your SVG kickstart! Thank you! You make other people happy! =) Keep up the good work!
