Blogging???

When the first time i heard my friend say blogging this word,my head is full of question marks. What is blogging? Is a type of program? Or a web to makes more friends like friendster and facebook?? (how poor is my english...T.T) After my friend explain give me what is blogging i just realise that blogging is such a good way to fill up your full time but I don't have the interest at all =X. The first blog i read was kennysia's blog, he is really a good blogger. You can read his blog at kennysia.com.
Actually i made this blog is to reply my friend's comment XD (too free le me...=X). Here is my friend's blog.
