BlogRush - Hoax or Real?

Just found this article about the new blog headline exchange service dubbed BlogRush via BlogNone site. Basically, a blogger has to register their blog and RSS feed with BlogRush, place the BlogRush widget, and then BlogRush service will automatically find the similar contents to your blog and place them in the widget. Your postings will also be placed in others' blogs in return.

The article argue that this BlogRush doesn't do any good except trying to boost their site popularity. I feel it's no harm trying it so I just placed it there. I've also got Google Analytics enabled in this blog -- will report back how much more traffic it improved.
