CAPTCHA is that annoying technology that asks you to type the characters in an image in a field to post a comment, get an account, or whatever. It’s a spam fighting tool, and one of the more successful ones I might add.

TIME’s got a piece on CAPTCHA which should be pretty interesting reading if you want to know about where it is originating, and what is being done to make sure that it stays successful. Personally, I hate it, but it serves its purpose and probably makes the web a better place, don’t you think?
