What is A Blog?????????

"What is A Blog?" This was the one question that would always pester me as I didn't know the meaning of Blog. I would often read it in newspapers and magazines and also hear about it in daily soaps and movies however I didn't know what did it actually mean? And I would be too shy to ask its meaning as I didn't want people to think that I am old-fashioned or something like that. So i avoided the "blog" like crazy.....then after a couple of days later I came across Ruddi who is my husband's best friend and he told me the meaning of "blogging". And I am so thankful to him for opening a window for me as i not only came to know the meaning of blog but at the same time I also found a way to express my thoughts and feelings through blogging.
