I love that you can pin, raise or lower results from specific websites. They also set it up so you can see popular raise/lower and pins. It's wonderful. Trust me too, it's worth it. ~850 searches a month here.
That sounds really interesting, have to check those out! I've only used that feature minimally so far.
