I wonder whether there's an RSS feed or something similar to notify one of new Blogger features when they come out.
You can now add a list of (public) followers of your blog and give people the ability to, with a single click, follow your blog... and that feature is now here.
Thanks to Cheyenne Palisades, who knew about it and took advantage of it before I did; I saw it in her blog.
P.S. Yes, I split an infinitive, but the alternative made it unclear whether the blogger or the would-be followers were doing something with a single click.
