Google web searches

Phew. I am totally exhausted. How on earth can people assimilate so much information at one time??? Do people really have time to go backwards and forwards between search engines? Hence the advantage of Dogpile and Metacrawler I guess but I didn't find them as detailed and fun to use as the others. I liked the Google wonderline and timeline the best. They were great. Wish i'd known about them before I did my assignments!! I found all options easy to use. The results , I felt, didn't differ too much between search engines. All relevant information was there and differed only in that they were obtained from various sources.
