6 rules for productive digital collaboration

It's no secret -- workplace etiquette rules have changed over the past 20 years. Digital communications have made it easy to shoot out short messages of mass information without the need for handshakes and hellos.

Of course, I couldn't help but throw my own rule into the pot. Glide over to Georgina's article and read my comment to find out my sixth rule of respectful digital collaboration. What else do you have to add to the list?
