For those keeping tabs on all things Microsoft-Live-related, the LiveSide folks have a few interesting updates. Microsoft launched on August 29 an official (U.S.-only) beta version of its Live QnA service. QnA allows users to ask questions, obtain answers and vote on the results. MSN Alerts have been rebranded “Windows Live Alerts.” A beta version of that service -– providing real-time scores, headlines and traffic info — is available for download. Microsoft also is accepting applications (through Sept. 15) from channel partners who are interested in becoming Office Live Early Adopters.
