...at this post, which is mostly uninteresting but ends with an extended discussion of the advantages of text messaging in the event of a zombie attack.
Consider this, you're at the park and suddenly there's a zombie outbreak. You're surrounded. What do you do? Call 911? Yeah, like they'll believe you. Under normal circumstances, you'd probably be turned into a zombie by now, but luckily for you, you've got TxtLJ.
Just whip out your phone and text, "postcomm.zombiekillers Umm...help, zombies are attacking me at the park" to TxtLJ (89855).
That'll post your message to thezombiekillers and you'll be rescued in no time*.
*TxtLJ should not be relied on in a zombie attack.
