If you like me you rarely use Microsoft Live / MSN then we both missed the launch (rebadging ?) of ‘Bing’.
It caught me by surprise when logging into the Microsoft WebMaster interface today and “boing” (with musical intonations!) there was the ‘Bing’ branding.
Apart from that the Microsoft Webmasters interface is still extremely underpowered functionality-wise compared to Google’s WebMasters Tools
If I cared more I’d research ‘bing’ and tell you more.
Sorry, you’ll have to bing it yourself.
