I am not impressed at all. I can find better ideas by going to topic related forums and simply asking other members for suggestions. More often than not the advice is not only good but those websites do not appear anywhere with decent rankings on the majors, they are passed on from one to another as being great websites for that topic. I think the majors have slipped away from being able to answer a simple search query. The whole point should be providing the most relevant result to the search query, not proving sites that have thousands of links or whatever.
