With more than 99% of the feeds with stylesheets just trying to do what we're doing, but without the knowledge of what aggregators the user actually uses and without the chrome privileges to subscribe them, not using our transformation on feeds that have a stylesheet would just make for a worse and less consistent experience for our users.</p></blockquote></figure><p><anchor-end xmlns="urn:x-suika-fam-cx:markup:suikawiki:0:9:" a0:anchor="14" xmlns:a0="urn:x-suika-fam-cx:markup:suikawiki:0:9:">[14]</anchor-end> <cite>Official Google Reader Blog: Namespaced Extensions in Feeds</cite>
