I'm not surprised that so many of you are equally as irritated as I am about this problem. Jabblog left me a link to a wonderful post on the subject, and I suggest that you go and read it too. It says everything I'd like to say.
If everyone started turning the word verification off and using comment moderation perhaps Blogger would get wind of our annoyance and do something about it.
I haven't tried the new interface because I'm too lazy to change something that seems to be working well, and now I don't think I'm going to bother.
Do let me know what you think about that post and pass it on to others who read your blog if you agree.
