Why do I blog?

Heather has a good post about why do people blog. Here is a list of my reasons:

1. I blog to put my thoughts down and to hopefully remember them.
2. I blog about my kids so hopefully I remember little things in their life.
3. I blog to keep family updated on what is going on.
4. I blog so that maybe, just maybe, someone would be interested in what I have to say.

So what about you? Why do you blog?
