An intuitive way to navigate the site's content. This assumes the user knows the correct product name and the rules you use to normalize it (ariel-atom vs arie+atom vs ariel_atom). This not the case for most URLs. I don't remember the exact title for each article in some blog. In fact, I'm more likely to remember http://example.com/?Article.view.1 http://example.com/?Article.view.1 than http://example.com/articles/2010/01/02/This_is_my_article_s_title http://example.com/articles/2010/01/02/This_is_my_article_s_... Please note the underscore between 'e' and 's'. Websites usually normalize their titles when putting them into URLs, and they don't just URL-encode them, because URL encoding looks bad. They use arbitrary normalization and shortening rules. Also, why would the user navigate via URLs instead of using website's UI? I think URLs should be reasonably short and have no junk, but I also think that the whole "put-words-into-urls" movement is driven mostly by SEO considerations that have nothing to do with user experience.
