The best advice I ever received regarding email was from my PR professor, Bill Sledzik:
“If you wouldn’t say it to someone in real life, don’t put it in an email.”
And today there are even more ways to embarrass yourself – text, Slack, etc. – especially with all of the integrated keyboards.
Think about it: In the age of loneliness will our need for human interaction lead to a tradeshow resurgence?
