What is blog for?

Isn't blog is for ppl to write all bout their life? its an online diary,except u can choose whether u want it private or not. It's my problem wat i choose to write here. i wanna write bout happy or sad stuff its my problem, because why? It's FREE! Internet itself is so called a free world. i dont care what u gonna say, i'm gonna keep on writing. just hope what i write next time is about some thing more into the livelier side rather den the dark side of my life.

All the best to me!~
