One of the more useful or annoying tools on the internet is CAPTCHA or reCAPTCHA.
If you have been here for a while you can guess I am not a fan.
While I do find it interesting from a programing perspective and I find the bots used to foil them just as interesting. My "real-world, everyday" dealing with it is not wholly positive.
I don't use it myself. I honestly don't get enough spam or bots to make it worthwhile.
I have run into cases where I was commenting on a blog and for the life of me could not get the CAPTCHA. If I am reading a blog with my glasses off then forget it, there is no way I am going to figure it out.
It really sucks and it's too bad really because the one of the biggest joys of blogging is being able to comment on others' blogs and getting comments.
There is an interesting post on this over at Clay Baboons.
I am not sure how many comments CAPTCHA has actually killed. In my case it killed one, maybe two, comments I would have made.All the the same, I'd rather turn it off here and maybe deal with some spam. I get emails on every post made, so I can usually delete the spam long before others see it.
What are your thoughts on this? My rough guess that it is about 50/50 on the blogs I visit.
