The Guardian: Why Google is the service of choice for sploggers examines spam, splogs, Blogger, and WordPress.com. As you may tell from the title, it’s overly harsh on Google, but nonetheless has some interesting commentary and information. Like I said last time someone wrote about this, I would never suggest WP.com is splog-free because I delete too many of them myself, but it is a problem we take very seriously and are ever vigilant against.
