  • It???s arguable whether the search engine deciding these things for itself is a good or bad idea; in this particular case, it???s good (both for SEO and for usefulness to users, it???s better, for a blog, to index only the front page, the posts, and the pages, not categories, tags, date archives, author archives, or anything else), but I can perfectly see how a webmaster wouldn???t like this.
