GrandCentral’s site is officially closing its doors on December 31, 2009. For those of you that don’t know, GrandCentral was the precursor to Google Voice (our favorite voice-mail service). Google acquired the startup and quickly started switching users over to their branded version of the service. No one is really sure how Google plans on monetizing the service, but they keep adding more features and also recently acquired softphone service provider Gizmo5.

If you haven’t started using Google Voice yet, then we recommend you start right away. Not only will you save time by reading transcriptions of your voice-mail but you’ll save money too by not having to pay for unwanted calls.
