Confused about Google's product offerings?

I have always found the UI's and the built-in documentation for Google's many software offerings (excepting their travel agent-like program) to be monumentally confusing.  Today I finally found a support person (by chatting with no fewer than seven different ones) who knew her stuff...

We Are All Ukrainians Now

This face reveals plainly the quintessence of the thing that National Defense is for. The life-long, KGB spy master has finally come fully into his own, but his character has never changed and has been as obvious as the contrived non-expression on his face ever since we’ve known him.

Voter Fraud Is Not The Same as Election Fraud

Two Huge Climate Messaging Errors

There has been and continues to be a long-standing problem with the way that methane is described as a greenhouse gas (GHG). The proper way to describe the strength of the various GHG’s using a pound of CO2 emitted (or a pound in the sky) as the benchmark would be to say A) How much heat is...

There are only two things that one needs to know to thoroughly understand our 45th President.

The first is simply that he harbors good will toward no one.
