If you do, there are some changes coming soon which affect the way you’ll follow content from Blogger blogs.
From the Blogger blog post:
…starting the week of January 11, we’ll remove the ability for people with Twitter, Yahoo, Orkut or other OpenId providers to sign in to Google Friend Connect and follow blogs.
We encourage you to tell affected readers, that if they use a non-Google Account to follow your blog, they need to sign up for a Google Account, and re-follow your blog. With a Google Account, they’ll get blogs added to their Reading List, making it easier for them to see the latest posts and activity of the blogs they follow.
So if you don’t already have a Google account you’ll need to get one and re-follow my blog (and other blogs). I know it’s a pain, but what ya gonna do, eh? :-)
