Can Anyone Help?

Hello to my Blogger/Blogspot friends out there.  We've been out of town for a week, and I'm just now trying to catch up on the blog.  I wanted to leave comments for some of you on your blog posts, and surprise, surprise, Google has made another change.  The commenting format is different, including the comment format on my own blog, and I can't seem to leave comments on anyone's blog.  I'm signed into Google, which it's instructing me to do, and still can't get to a comment box.     Is anyone else having difficulty with this besides me?  I love blogging, but I seriously question why I keep bothering with Google.  I've been to the Help section, and my husband has tried to figure it out, and we're at a loss.  Would appreciate any wisdom you guys have on this!
