I've just tried out a blog called The One-Minute Writer. They give you a prompt, and you have just one minute to write about it. Believe me, it's not long. It was kind of fun though; I may try it again some time.
The prompt (from here), is:
Do you think high school is easier or harder today, than it was 50 years ago? Why?
My Response: High School 50 Years Ago
There's no doubt that high school was a lot harder fifty years ago. Just ask my grandfather. He had to walk five miles to school, sometimes in the snow. He was caned for frowning or not doing his homework. At the end of a gruelling day, he had to walk seven miles home again, in the blistering heat.
