I will give $50 to the best idea for something a search engine needs to have, it would help if your idea was unique, for example a porn warning notice ect, I should have permission to use all ideas and only 1 person can win. PM me your idea, do not post on this topic!
how about something in regards to a 'relevance' meter like wikipedia uses. like the most relevant things appear first rather than just pages which have been SEOed.
How about a simple thumbs up or thumbs down that people can select if that site was relevant? It would also be cool if there were an uber search engine that could give you a scroll down list to choose to search just sites like youtube or digg if you wanted videos or news. Imagine if you could have a youtube search option so when a user types in the desired video they get taken to youtubes search results. You could do this with all sites.
