Thanks everyone for taking a look and giving feedback. Thank you especially to the folks who gave me bug reports that I can take a look at and try to fix. Most of the technical issues raised are fixable but a few are not. SEO is fixable by following the Google ajax SEO spec. Accessibility and other issues with selecting and highlighting text are not. Many of the other criticisms could also be levied at other javascript heavy sites (e.g. Facebook). It's clear that many people are philosophically opposed to rendering websites in Canvas because it reminds them of Flash and is incompatible with the semantic web. I guess the proof will be in whether or not web consumers end up thinking it is cool or not. That remains to be seen. Personally I think this approach opens up a lot of interesting possibilities. Anyway, thanks again for your interest and responses, even if they were largely negative. :-)
