This blog reader is not enjoying the new CAPTCHA - and has a problem with using it, repeatedly.Why do I have to click on 3 pictures of steak, to post a comment?
When you comment, you now have to identify yourself as a person - not a robotic process (aka "autobot" or "bot"). For most of us, this is not an issue. We login to Blogger (or Google) once a day, and we're done.
The "once a day" solution does not work, for everybody.
Some people have to prove their identity, as a person, repeatedly during the day.
CAPTCHA use is remembered, for most readers - and not repeated.
Long ago, Blogger comments used to allow "anonymous" comments, when selected by the blog owner. That option allowed too much spam comments, so Blogger added a non optional "CAPTCHA" as part of the anonymous commenting process.
To make CAPTCHA use more acceptable, Blogger designed the CAPTCHA to function as an "anonymous" login. with use of the CAPTCHA remembered during the login session. With cookies properly permitted, a reader can identify as a person once - and not again, until cookies are cleared or the browser is restarted.
The original CAPTCHAs are not a challenge - to some hackers and spammers.
The original CAPTCHAs were number or word puzzles, where you would be shown a sequences of letter or numbers in one window, and asked to re type the sequences in another window. This allows each person to identify her/him self as a person.
The person authentication process is trivially duplicated, though, with "CAPTCHA solving" services. "Pay to Verify" is one CAPTCHA solving service, that is part of some hackerspammer portfolios.
The reCAPTCHA should restrict spammer activity, yet permit reader activity.
The new reCAPTCHA requires a sequential solving process of multiple challenges and responses. This "challenge / response" process should force the hackers and spammers to find a new way to provide "CAPTCHA solving" services.
Unfortunately, people who can't manage the cookie filters on their computers will, in some cases, have to "login" repeatedly - and this will require more patience from some people. Proper cookie filter management may require an understanding of what cookies are - and what they are not.
Choices made by both blog owners and readers will affect the new CAPTCHA.
The "login" process will vary, based upon choices of the blog owner and reader. Depending upon the blog hosting the comments, the commenting options permitted by the owner, and the option selected by the reader, a reader may have to enter letter or numbers, have to solve a visual puzzle, or login to Google.
The new re CAPTCHA ("visual puzzle") will require some work, by the blog owner, to install on each blog. And, it won't please everybody - but it should provide an improvement in spam free comments, and better reader options for commenting.
If you have a problem with publishing comments, one of the simplest problem diagnosis starts with checking / correcting the browser cookie filter.
