Whats a blog?

I heard this weird word the other day "blog" and I thought I had heard it before.  Well it turns out that I had heard the word before and that I even had one.  I can't believe that I had forgotten all about it.  Maybe it has been because of these four and all the time I spend with them.  They always seem to put a smile on my face so I thought I would share a little... go ahead and try not to smile.
