If you’ve been having trouble commenting on the blog using your Google account, as I have, it may be because of your cookie settings. From Blogger’s help files:
Blogger uses third-party cookies so you can comment from your Google Account. If third-party cookies are disabled on your browser, you may not be able to comment on blog posts while you’re signed in. You can still comment anonymously, or with a name and URL.
In Chrome, which stats say most of you are using to read this, you can enable third-party cookies by going to Settings > Privacy and security and then select either Allow all cookies or Block third-party cookies in Incognito.
If you don’t want to allow any third-party cookies, you should still be able to comment by choosing Comment as Name/URL in the commenting dropdown.
If this works for you, could you leave a comment and let me know?
