Make sure you are not a computer

Grammar says everything. The online signup process for Nimbuzz, one of the wifi telephone services, asks users:

“To make sure you are not a computer, please type in the characters you see in the text box below:”

In other words, you can find out if you are human or computer by taking their simple test. Imagine if such a test were available to the androids in BladeRunner.

At least we all now have a place to turn if we are afraid we might be computers.
