Well please remember that filter usage in general has been minimal because
filters haven't been available cross platform until IE10 and Safari 6 (aka
the last year). On Android browsers, they're still only available on
Android 4 on the latest Samsung browsers. There have also been showstopper
bugs on each browser (not to mention that light source positions are still
not correct in Chrome and document fragments are still not supported as
inputs on Firefox).
