Funny, I was just thinking about that search engine. I used it a few years ago and will probably submit to it again before the end of spring. I don't remember having spectacular results but even a little action is better than nothing at all!
Give it a try using a different search engine. You might be surprised. There is this add on in Firefox so that you can search from various different search engines from the tool bar.
In general I still think that Google has the best results when you are looking for something specific. I just dislike the idea of one company having such a large hold on any give market or industry.
I find that Google has the cleanest interface and is the least obtrusive when searching. I understand there need to be ads but they shouldn't be difficult to identify.
