...I always was/am frustrated by websites who confront me with 2 hardly readable words (more then once I need to re-generate the words, exactly because of that reason) that I then need to re-type. When you think about it, it is just really annoying and far from userfriendly.
Obviously platforms such as XenForo do not suffer much (if at all) from this re-captcha thing when it comes to the usability, since we are only confronted by it once per registration. Still... I hope that by
next Xmas a new re-captcha child is born
