Why do you have a blog?
I first started keeping a journal because of Doogie Howser.
Yeah, I hear some of you snickering back there. Laugh if you will, but I always thought the computer journal thing at the end of each episode was pretty neat.
My journal started off as just a simple database using Appleworks on my Apple ][e. Then it changed to a series of notebooks (most of which have since been tossed out by my parents in the Great Cleaning they did a few years ago) during my undergrad and grad school days.
Now I blog.
To me, blogging is just an extension (a very public one at that) of journaling. To others it's something else, but to me just an online journal. Since I'm just really bad at picking up the phone and calling people (emailing and IM'ing too), I use my blog to let people know what I'm up to, talk about or show off anything interesting I encounter and spill out some of the random things that the voices in my head tell mecross my mind.
That's why I keep a blog.
