Err... WTF?

[bazzargh]

I assume it's a reference to this comic about code reviews:

http://www.osnews.com/story/19266/WTFs_m

(so really, the counter should also show the rate of WTFs per minute)

[joshka]

Yep. That comic was the inspiration. WTF/minute is the end goal (amongst other metrics). Feel free to add any other suggestions to the uservoice site (click the WTFeedback button at the bottom of the page).
