This interview may be a good read. It deals with some aspects of the "current state" (June 2010) of SVG implementations.
It's got a really sweet format. It's a two-sided interview, meaning that Doug Scheppers and Patrick Dengler interview each other. It's not often that I come across interviews that are interleaved:
I asked Patrick some questions, and he asked me some.
To read about technologies that I may (or may not) get a chance to explore is super enjoyable. This time, my favorite was: an HTML version of SMIL called HTML + Time.
The interview has an addendum :)
