Does it make sense for MySpace profile pages to rank on the first page for one of the 10 most competitive terms on the web? Should English to English page translations inherit domain authority from another domain? I don't want to out anybody, but I see way too many tag pages ranking in Yahoo!'s search results. The easiest way they can improve their search results is to simply delist any page with tag in the URL.

If they continue down this path inside a few months they will link to nothing but internal site search / tag pages on other sites. Where is the value, innovation, or thought process in that? What percent of Yahoo! searchers want to see Wordpress.com tags pages and how many Yahoo! Pipes pages are tagged with a brand name? What does a searcher do when they land on a page like this?

If you are going to trust user generated content on authority sites, expect a lot of users to create content just for Yahoo!. :)
