[Mithaldu]

Sarcasm is a highly inefficient mode of communication and should be avoided as much as possible.

[nileshtrivedi]

It's inefficient if your assumptions about the audience are wrong. If you know your audience, sarcasm is highly effective, high-density mode of communication.

[Mithaldu]

Got it, only with close friends and family.

[ExpiredLink]

Only with intelligent people.

[brazzlemobile]

So should off topic pontificating.
