If you have a blog with captcha's, I'll only comment if I REALLY want to. But I'll hate you a little inside for making me squint.
So yeah. Make the captcha's go away. You'll thank me for it. Actually, your blog readers will thank me for it.
(I haven't had mine on in at least a year and have never gotten a spam comment. so there.)
(I don't know this blogger but they have a "how to" make them go away.)
(these are the things that annoy me while I'm in my TWW)
