I thought it sounded pretty silly, too. I gave the free trial a shot and for technical searches it was the best I had seen by far. Being able to lower certain sites and raise other sites makes it much easier to filter through shitty results like blog posts and stuff. I pay for it now and it’s worth it to me just for the time savings on technical searches. It definitely is still pretty far behind for things like local business info and stuff, but as a general purpose search engine it’s been extremely good for me.
