C|Net , reporting from the AlwaysOn Conference has a story quoting Blog Maverick Mark Cuban about why he is relaunching his IceRocket.com search engine as BlogScour:

""I seemed to get the same responses all the time…I wanted something that let's me know a blogger's consciousness," Cuban said during the AlwaysOn conference at Stanford University here.

So the man who resurrected the Dallas Mavericks and took on Donald Trump in the reality TV game said he will soon relaunch his IceRocket search engine as BlogScour. Similar to Technorati or PubSub, Cuban's BlogScour will search for the latest postings across the so-called blogosphere and return a list of results. The revised IceRocket is expected to be unique among the other search engines in that every search entry has a thumbnail of the home page of the listing."

UPDATE: Additional comments have made it clear that BlogScour will be a spin-off from and not a replacement for IceRocket.
