That should read "have fallen over time and will continue to do so".
See http://www.captcha.net.   They don't seem to be the ones usually
used around, but their reported accuracy rate is higher than my human
accuracy rate for the ones I do see.  If they make these tests much
harder, I'll have to write a program to start signing up to groups and
posting comments on blogs, or hire a captcha reader consultant.
