Quora and Pinterest... one has cornered the text-based SEO-spam segment, other has cornered the SEO-spam image segment.

Pintrest stays in its lane and it sounds like actual users can benefit from it for their own needs. It's only annoying if I need a quick image snip.

Quora can and will pop up for nearly every search query and I've never been satisfied with the answers I peek at, ever.

pinterest can be better if you are actually there to use it (ie not directed from search traffic)
