Google Gmail recently finalized its “Undo Send” feature
Google’s inclusion of the feature seems to reflect a recognition that the speed with which technology makes it possible to send email can make us more inclined to send messages mindlessly, and that we need to be protected against ourselves as a result.

You might say that there is an Internet Corollary to Treebeard’s Law: “It takes virtually no time to say anything on the Internet. Therefore we will say virtually anything on the Internet, even if it is not worth taking any time to say.”
While I can admire the motivation behind Gmail’s new “Undo Send,” perhaps we could all strive to make “Undo Send” unnecessary by mindfully observing the “Send” button and only clicking it after we have drawn the considered conclusion that the message we are about to send is worth saying–and that we are ready to stand behind that message without regret.
