Thanks for the feedback!
I agree completely, but in thinking about it, CSS has got to be easier to understand than English! Googlebot sure hasn't got this down yet. (Some bad english in these sentences.)
One reason I'm asking is due to the release of Expression Web. It's clear quite a few web masters have been astonished by this release. Useful features have been gutted only because they were poorly implemented or implemented in a non-standard (because there was no standard) way. The features were useful and could have been re-engineered with new technologies and adhered to standards, perhaps even transparently to the website user. (But probably not to Google, thus this thread)
One possibility in the near future is massive conversions of sites with things as simple as font tags versus styles. I'm not sure I've seen a lot of discussion about the impacts of this type of change on web page ranking in Google SERPS.
Does Google not even understand a simple style applying a font? If not, converting to style sheets in essence removes all the formating information Googlebot used to see.
I have seen postings by quite a few webmasters who have "re-engineered" their sites and have found their rankings go down the tubes. I have also seen some who have redesigned and apparently had few or no problems.
In the past I've had ranking problems (and Adsense problems) because Google was parsing footer and navigation information. Putting this extraneous non page specific information into IFrames improved rankings and Ad targeting. Expression Web will basically drive many webmasters into reformatting their entire sites navigation mechanism and perhaps header and footer design. (I know some/many will say don't use EW!)
I've just fiddled a little bit, a couple of times, with one or two site's navigation structures and have seen some indications the changes were doing grave harm to page ranking and pulled the changes, fortunately for a fairly quick recovery.
Anyway thanks again for your thoughts.
