Years ago, the backronym “Yet Another Hierarchical Officious Oracle” (YAHOO) was born out of Jerry [Yang] and David’s [Filo] Guide to the World Wide Web and became the first successful Web portal. Later, Amazon.com’s model was the one everybody tried to copy. And now, it’s back to Yahoo. Yahoo updated it’s home page last year, and now, AOL is launching an eerily similar version in which not much more than the name changes. Is this infringing or just down right poseurish?
