If you have two or more email addresses, you've probably fallen victim to all of those pesky tabs and accidentally sent a message from the wrong account. But if you operate a Twitter account for a major company and also have your own personal account, those sorts of mistakes can be slightly more dangerous.
Take this random tweet Thursday from the NFL on CBS.
That was sent our way by @xSmootx on Twitter, who figures the mistaken tweet wasn't deleted for about 10 or 15 minutes.
These things happen. Pretty harmless... unless of course Wells Fargo has bought itself one or more of those $4 million, 30-second ads on CBS during next Sunday's Super Bowl.
If that's the case, well, then, pretty harmful, and CBS will "love" explaining this one to executives at the fourth-largest bank in the United States.
