For those of you who are not familiar with the term, a CAPTCHA is a feature on many user populated websites, such as Myspace with the purpose of blocking automated programs from spamming its users and for overall security. Here is how it works:
A user is required to enter a random letter and number password into a form before being able to submit information, log in, etc. This password is essentially given directly to the user in an image, rather than in text form, so that an automated program cannot detect the characters. The password the form field expects is the same as that shown on the image, but this sometimes causes problems.
Jeff Atwood at the Coding Horrors blog discusses whether CAPTCHAs are dead. This follows a news report that scalpers probably beat the CAPTCHAs at Ticketmaster.
Jeff links to a Chinese site that sells CAPTCHA decoders. The site quotes different prices for breaking different CAPTCHAs. An eBay decoder, for example, is being sold for $4000 and claims 70% accuracy.
What caught my attention were the unbreakable CAPTCHAs in the list. The Yahoo CAPTCHA is listed as unbreakable. That isn't surprising. Most of us can barely get it right ourselves.
Consider a Yahoo CAPTCHA. Sometimes you cannot tell the difference between a G or a 6? And the way that letters are often skewed, the difference bewteen certain uppercase and lowercase letters is virtually unrecognizable?
Contrast that with a Google CAPTCHA also listed as unbreakable. The Google image is clean and legible. Most of us have no difficulty getting it right. Google demonstrates that effective CAPTCHAs don't have to be unfriendly to users.
I am curious to learn which CAPTCHA libraries generate strong, yet user friendly challenges.

I wanted Alexa to know about "ALL" visitors my traffic exchange website was receiving, not just traffic from their toolbar users. I wanted them to know not because I support them, but because so many other users did. Users that were apparently unaware of the traffic-ranking prejudice. I accomplished this by installing the Alexa traffic rank banner on all of the pages within my website.
The Alexa traffic rank banner is a free advertisment for them. Adding their banner to your site is a small price to pay for the increase in traffic rank. They offer several types of banners in different sizes, so it should be easy to one that fits your pages.
Since installing the code on January 15, 2007, the traffic rank for checks4free.com had improved by over 4.5 million within 15 days. That does not mean there was that much traffic. It means that the website had moved up the list from the number 6 million spot to approximately the 1 million spot.
You can view the Alexa traffic rank for the Checks4Free Traffic Exchange using this URL: http://www.alexa.com/data/details/traffic_details?url=checks4free.com.
If your website has a low Alexa traffic rank, I hope the suggestion in this article will help you to improve your ranking as well. The help file on the Alexa website talks about the biased ranking. However, to the millions of users that base an opinion about a website using the Alexa traffic rank, numbers speak louder than words. Your only other option is to hope that more Alexa toolbar users visit your website.
