Blogger weirdness

I see that Blogger is busy being weird again. Word verification seems to have become the default on a number of blogs that never used to have it. Even weirder, on a couple blogs I visit regularly it's now impossible to leave comments. The comment box is there, everything looks normal, but when I type the cursor moves but no characters show up on screen. I have no idea if the comment is registering or not. Very, very strange.
