Are you satisfied with search results?

I think it could be really useful to build an extension that you could use on top of a classic search engine to make your results more relevant and personalized to your personal search history. It would compare the results with other pages you visited for example and try to evaluate whether or not said page would interest you.

But first, I want to be sure people would actually find this useful. Do you find the results of your online searches are quite useful and relevant or do you often have to search a long time to find useful websites?

Thanks!
