Is there the inkling of thought given to the prospect of bias within the mechanism between search relevance /quality between the utilization of a browser that is not aligned with the search engine being deployed? Say a IE user utilizes Google - and again this is perhaps a concern going forward more than it is at present - or a Chrome user searching via Bing - that the inferior compatibility may hinder or otherwise unduly influence search results from an end-user and/or SEO's perspective?
