Keep out the comment spam bots! On the receiving end of much internet spam roach droppings, I understand the use of captchas, those random letter combos generated as graphics, intended to keep out the automated spam bots on web submission forms. I have used them myself.
So I like them when the work for me, but oi! I cringe when I have poured my eneergy into writing the perfect comment and eager to see it posted, and Zam! I am forced to squint at some obscure twisted set of letters and punch the into the box. It really does short circuit the connection experience you just made with a blog writer and your communication. It completely drops a trap door open on your usability experience.
But okay, necessary, small evils we can live with.
What I do not like living with are crappy captchas, the ones that make you work hard to decipher, like this one:
While this one is rather legible in terms of the numbers/letters you can see (as opposed to some of those twisted ones on Blogger and elsewhere), if I did not bother to read the caption, I would not have thought there were five characters to monkey type in the form it sure looks like C484 to me. And don’t you wonder on these things:
What if I get it WRONG? Does it eat my comment, does it put my IP address on a bad list? (I know the answer, but it is not obvious to the victim)
Sigh, one more thing 98% of the web needs to jump through hoops for due to the abuse of its open-ness by link spam harvesters. This could all change in a heart beat or two, if Google woke up, smelled the spam, and took away the incentives that link rank creates.
Ouch, I keep dreaming.
