Netspeak is annoying only when not done intentionally by people who obviously would't use it. If a poser tries to use it intentionally, it's just more annoying
Also, I remembered the episode from my youth.
Setting: After lunch at Pre-school
Cast: Myself, my class, my teacher, and the cute boy named Adam's little sister Samantha.
Summary: We were told to be quiet until our teacher came back. Sitting at our little tables, Samantha starts saying the word "topsy" over and over and over again.
"Topsytopsytopsytopsytopsytopsy" and got louder and louder. Our efforts to silence her were in vain.
We all had to put our heads down until our parents came to pick us up.
Since that day, I have not liked Samantha or the word "Topsy". One of our cows was named Topsy, and until we sold her, I was never very fond of her.
