Google has launched a tool to find blog info from outside their domain. They will tap into the RSS or Atom feeds to do this, challenging Yahoo who is beginning to dabble in this. On cnet.com, a story today outlines how this would work. At http://blogsearch.google.com you can search for your topics and go. I tried it out and think it is probably going to be a good thing. If anyone has tried this tool, out let me know what you think of it.
