I've had a link up in my sidebar that allows people to subscribe to this blog by email for a while now. I realized, belatedly, that it relied on Captcha, which is short for something I'm not remembering now. Basically,, it's a device for keeping spammers out, and allowing humans in. It's that little thing on almost every account sign-up page that says "type the numbers into the box below." It's great, except that a lot of times, there's not a good way for someone with a visual impairment, or other reading impairment to access the picture. It's blurry, it's an unlabeled picture, and it's the bane of my existence.
Fortunately, the picture (punn intended), is getting better.
Feedburner just added audio versions of their captcha to email subscriptions.
This still isn't going to help anyone with a visual/reading impairment and hearing or audio processing impairment, but it is a step in the right direction.
I'm glad to see that this service is available. I think a lot of bloggers want to do the right thing. They don't wake up and try to lock people who are blind out of services and extras available on their blogs. But most bloggers aren't skilled enough in programming or simply don't have the time to spend writing code for everyfeature on their blogs. So, their counters may not be accessible, or, like many, they're forced to choose between captchas that lock blind people out, and no spam protection whatsoever.
Some of the blogging platforms use audio captchas, but others don't. I'm unable to comment on some blogs because of these captchas, and other blog owners who don't have them enabled because of this issue still have to contend with spam.
I hope that some day soon, we'll have the ability to avoid spam and allow everyone to comment. Thanks, Feedburner for
Showing everyone that audio captcha can be implemented quickly!
