Well, that was interesting. I go to sign up for blogger.com and find out that not only is natescape.blogspot.com already taken, so is biodieselnow.blogspot.com and even natebyrnes.blogspot.com! Egads.
The moral of the story: go ahead and sign up for any sites you might want to use sometime in the future.
After writing this post, I'm going to go out and reserve some blogger names for my kids, in case they ever decide to become a blogger. My daughter loves to write, so who knows?
