Is cyber defamation provision necessary?
….Incessant online gossip appears
to have been largely to blame for
her death…….
* source: www.times.com
…. South Korean police have since announced that they will crack down
on online defamation, but little has been said about the late actress's
problems as a single mother in this deeply conservative society.….

9. Are these issues unique to Korea?
If not already,
it will happen later
anywhere in the world;
as the internet heads to the future.

Take Away
• The resulting social power shift
- Consumer & citizen-centered
• The engine of innovation
- Stimuli for change & transparency
• Still in the earlier stage of internet revolution
- Our mindset & culture uncomfortable with internet
- Still far from ubiquity
- Digital divide among countries & regions
• Should strive to harness the full potential of internet
- Redefinition of copyrights

10. The Road Not Taken
Robert Frost (1874 -1963)
Two roads diverged in a yellow wood,
And sorry I could not travel both
And be one traveler, long I stood
And looked down one as far as I could
To where it bent in the undergrowth;
Then took the other, as just as fair,
And having perhaps the better claim,
Because it was grassy and wanted wear
Though as for that the passing there
Had worn them really about the same,
Yong-Kyung Lee 19
And both that morning equally lay
In leaves no step had trodden black.
Oh, I kept the first for another day!
Yet knowing how way leads on to way,
I doubted if I should ever come back.
I shall be telling this with a sigh
Somewhere ages and ages hence:
Two roads diverged in a wood, and I—
I took the one less traveled by,
And that has made all the difference.
