Now people are more naked for google to see what they do :p
On SEO context, since google uses chrome data extensively (few of the ranking signals attribute to chrome usage), so it could be not so good news for SEOrs.
Size does matter, pretty soon we will see few good SEO plugins popping up for chrome. Existing one's are not that great.
Albeit better content and high quality links can still win the race so old hand still rules :)
