Your blog probably have an “Archive” page like this one where you show all your pages, categories, tags, monthly archives, authors, etc.
But wait, do you really need an archive page or an HTML sitemap page? Of course, you need an XML Sitemap for your blog like this one but it’s for search engines and not for users.
Unless you’re a real big brand, your visitors don’t care about your Site Search, or even your category or tag cloud. People are too lazy to search your blog to find interesting content.
