Hey folks,

I just wanted to offer the reCAPTCHA team's willingness & desire to 
contribute in discussions relating to CAPTCHA implementations. When I was 
talking with Gregory off list, this topic came up, and I mentioned that 
many CAPTCHA-discussions have lead to bad results when people who have not 
implemented CAPTCHAs weren't involved in the conversation. A comic example 
of this was captured on xkcd:

http://xkcd.com/c233.html

The "cartoon" is simply a drawing of a web page that says "To
complete your web registration, please prove that you're human:
When Littlefoot's mother died in the original "land before time",
did you feel sad? <radio button> yes <radio button> no (bots: no
lying)"

We'd like to see CAPTCHA related discussions result in recommendations 
that can be implemented in the real world and that can be used even in the 
face of skilled attackers yet are still accessible to a large number of 
people. I think we can best achieve this goal by working together.
