In its continuing efforts to remain the most useful web company on the planet, Google introduced free telephone calling from Gmail in August of 2010.  Although I’ve used it only a couple of times, it worked incredibly well, with excellent call quality.

Recently, Google announced that it was continuing free telephone calls for U.S. callers to the U.S. and Canada through the end of 2011.  That’s good news for anyone who makes a significant number of telephone calls.
