What is your biggest flaw?

If I had to do a job interview, I'd use this as my one and only interview question. The responses fall into several categories:

1. The overly-scripted response. This person has played the game, knew that you'd ask that question, and has a statement ready. Although this is generally good, if you can tell it's scripted, it defeats the purpose. This person is out.

2. The "I didn't think you'd ask that question, but I'll make up an answer I think you'll like. These are the worst. Usually the responses include "Being overly punctual" or "Caring too much about the quality of my work". Did that line get you hired at McDonalds? Yeah? Then go back there.

3. The "I don't know." Honest, yes, but come back with something, anything.

4. The real response. Most people either don't know this or won't say it.

I think my "real response" would be my tendency to make blogs and not update them.
