Why do ppl write blogs

Frankly speaking i dont know why i write blogs. During my IIT days i used to read the blogs of Saurabh Nanda who used to post some cool linux stuff there. But do we write blogs for information??? I guess NO!! I think most people (like me) write blogs when they get frustrated from work (or life) and then blogs is a medium to take a break from work and post all ur frustration . Some day you may look back at those pages and smile :). Other than this , you may also have a secret admirer :))
