Commenting on Blogger Blogs

I, as well as a number of people I know, have been having trouble commenting on Blogger Blogs, so I figured I'd post what I found to help...

I was able to type a comment, but then it would send me to sign in, and then do the letter authenticator, and then i'd be back at the sign-in page, thus starting a continuous loop.  Using my dear friend google, I found a few tips.  What worked for me was either deleting my cookies, or un-checking the "remember me" option when signing in.  For some reason it worked.  Who am I to wonder why?
