I have discovered what the problem is with why I can't comment on sites with word verification on them. And it's not just Blogger sites. Jeff Goldstein uses MT (I believe) and I can't comment there, either. Too bad, too, because he wanted some input on a new direction for his blog, and I wanted to say "Needs more tits!" but I was unable to.
I've found out that the verification thingies use spyware as part of their code. Adware. Fastclick and Doubleclick and such. My protection rebels against them, and I'm just fine with that.
So, if I'm not commenting on your blog, it's likely not because I don't like you, it's because I can't. And I won't.
No big loss.
