Yahoo! is a website that provides free e-mail, and also has a search engine and chat rooms, along with an instant messenger service. It is correctly spelled with the exclamation point.
I find it humorous when people say that Yahoo!'s search engine is worse than Google's, because Yahoo! uses Google's search engine to get results. Thus, no matter which one you use, you'lll always come up with the same results.

Email service/search engine/news site (sort of) that does fairly good with the e-mail and search engine parts but is either passing some stupid story about a worthless celebrity either wearing something they consider weird off as news. When they do talk about real news, the comments section is always filled with republican nutjobs who have no idea what they're talking about.
I have a Yahoo! account. Good with emails, bad with everything else.
