This days everyone knows what spam means, just a very annoying way of marketing that eveybody has tasted.
Many popular sites started using the CAPTCHA methodology to avoid automatic registrations via BOTS since year 2000. Sites like hotmail, yahoo, gmail and others are using this method to avoid 'automatic account creation'.
CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) developed by the Carnagie Mellon University, was broken a weeks ago. It just matter of time to start seeing spammers with Gmail account and other sites being violated.
If you have a site that use this method to keep BOTS, outside your site. Be aware that CAPTCHA is not longer safe.
Since, CAPTCHA was developed by Carnagie Mellon University. Can we expect some solution by Google?. Lets think about that for a minute Google has always overpass everyone expectation with many contributions and probably they had already started some internal research on this. (This is just my assumption, i haven't heard anything official yet).
Lets wait and see what happens. :D

I don't think that CAPTCHA being broken poses a threat to the users, other than perhaps getting more spam now. In fact, several CAPTCHA sites based on images could be broken before if the images weren't complicated enough, using OCR (I think that's what it's called)
I think one interesting solution to the problem is this type of tests:

It may seem silly, it may be a slower process, but it works.
I can't be more agreed with you ivan, OCR (Optical Character Recognition) is a tecnology developed to translates images to text.
Im just a google fans solutions,
since whatever google offers to the public is always good :D
