The only airline I know that encourages extra contact with pax is southwest. They do preface their encouragement by asking pilots and crew to only do what they are comfortable with. If humor and joke telling are not your forte than stick to canned announcements.

I think we deltoids need to step back from a poorly worded bulletin and think about the companies goal. Customer interaction and communication. Just do your own personal best and nobody will fault you. Just stop with the resumes though!! Sheesh!
