The MSN Spaces Team has announced a change in URL's of all blogs hosted on MSN Spaces. If you have a blog address like http://spaces.msn.com/billgates, your new URL on MSN Spaces would be http://billgates.spaces.msn.com - Oops, looks like a complete story in itself.
OK, though the old URLs would still work and visitors will automatically be redirected to the new address, it will have an huge impact on your search engine rankings. The new MSN spaces URL will be treated as a new website by Google and other Search engines and may even face the Sandbox effect.
This may be the worst nightmare for someone who plans to monetize his site.
