Why blog?

Yes, why blog? That was a question I asked a friend after I found out she has a blog.
Her answer? Well, everybody else seems to be doing it ....
Not me though.
The thought had never crossed my mind.
But then again, as I started reading blogs and finding out that there are soooooo many types of blogs, maybe there is room for one more: my blog.
We'll see, once I get the hang of it, there might even be postings worth reading here ....
