I guess it is more than an year now, when I was trying out some service (possibly search related) at hotmail.com and they had an option about giving some feedback to them. At that point no search engine provided a search facility that dealt with a simpleton querry like - "Where is TajMahal?" and gave more precise answers to this querry rather than loads of results. I had filled in that feedback form, if hotmail search engine could provide such kind of features in (then) near future, it could put it differently ahead of other search engines. No feedback came from them. Well, it couldn't have been expected either as the been-filled-up form mentioned not to expect feedbacks.
Came across an article on slashdot that mentioned about google providing similar service now. On further readups I found couple of other projects and search engines (www.answers.com) that were giving similar services good enough.
feels happy that as a user of search engines I felt a need for improvement there that voila! somebody has even taken steps towards that.
