Most companies tell employees what NOT to Tweet about, but Tony Hsieh, CEO of Zappos.com, suggests to employees that they Tweet about these three things:

1. What will cause my followers to smile
2. What will enrich people’s perspective
3. What will inspire

Thanks to Hollie Delaney of Zappos.com, for sharing this yesterday during out social media session at The Conference Board conference on extending your brand to employees. Thanks too to the other super-smart and generous panelists — Marietta Cozzi of Prudential Financial, Kat Drum of Starbucks, and Kelle Thompson of Liberty Mutual.
