Google's new blog finder

Google has a new feature whereby you can find blogs by the bloggers name, or topic. I tried it with my name and then my name + a topic and found it very easy to use. http://blogsearch.google.com. However, it also makes it easier for the blog spammers to be target specific. These are the "Hi, great blog. Come and visit mine on [your topic]. So I'll have to add the stronger filters to the comments. My topical blogs are all getting hit.
