Two new punctuation marks ...

I have now seen so many pages on the web with the basic :)s and :(s and their good/bad variations that I think at least the English Language should consider having these:

• :) - implies mischief, happiness, light-hearted mood etc.
• :( - implies being dejected, sorrow etc.

as standard punctuation marks in print.

What say?
