From the article reCAPTCHAs are finally readable by normal humans:
Google today announced that reCAPTCHAs served up to humans are finally readable without the need to squint your eyes or bang your keyboard in frustration after typing the wrong sequence of letters five times in a row. Who can even read those things, amirite?
I'm glad Google is making CAPTCHAs easier for humans to read. For the very, very rare times when they're necessary, that's a good thing.
However, I want to make an appeal to the thousands of developers who are thinking of implementing a CAPTCHA to deal with their site's form/registration spam: use CAPTCHAs only as a last resort.
CAPTCHAs: The nuclear option.
