Cell phones hands down.
When you're texting in places like church, the bathroom, etc. it's time to re-evaluate your life.

I've been meaning to start a new one of these, and finally got around to it.
I figured it's a new year, I'm 18 now, and I hated the old one so why not?
It's just a pain in the ass starting it up, but I have high hopes for this online journal.
