Hello, I have a site at that looks a lot like pinterest, it uses drupal as the "engine" and the rest is a theme.

I was wondering how can I add a filter section (like in the adult pinterest sites out there *ex.com) where a user can filter out which content he has no interest in.

my site is pinsabout.me and I really would love to add that functionallity into my site.

Can any one help me (with very non-high techie jargon) on who to achieve that?
It would be greately appreciated, it would help me get my site at the point I want and be able to promote it.

Thanks
Nathan
