It sounds like Mark Cuban and IceRocket are changing the name of the IceRocket's blog search at the URL blogs.icerocket.com to Blogscour.com sometime in the near future since you will notice it already redirects to IceRocket. Mark recently mentioned the change in this blog post. He then goes on to explain the reasoning for this change in his very next post here which goes on to ponder if a blog search should be a tool created with bloggers in mind or if a blog search as a tool that should be created for normal web search users. It sounds like IceRocket's is aiming at providing business people and bloggers alike with up to date information on business, industries and other types of information that are dear to them. I agree with this strategy in that many of the features can be offered to please the masses since I think eventually normal website users will catch on and use the blog search engines regardless of who the features are build for. I just wonder how IceRocket will transition the tagging that they currently use to Blogscour. For additional information on Mark Cuban and IceRocket/Blogscour check out this post by Paul Chaney.
