New Microsoft Small Business Directory

Looks like the bcentral directory is bye bye. Microsoft is making way for the new Microsoft Small Business Directory...My only question is why? Sounds like pretty much the same directory. Here's a snippet from an email I got today.

Continued listing on the Microsoft Small Business Directory
Also effective May 18th 2007 at 3:00pm Pacific Daylight Time, the bCentral Small Business Directory will be retired. In its place, we are offering existing Submit It! customers and others who currently have bCentral Small Business Directory listings a free, grandfathered listing in the new Microsoft Small Business Directory. While we will be preserving the present directory’s link friendliness and search ranking value, slight changes will be made in the way the directory appears to the public and how you may alter your listing.
