Could not detect a feed for this URL. Add URL anyway?

Have you tried adding your friend's blog site or website in your blog roll and a message tells you:

Could not detect a feed for this URL. Blog posts and update time will not be shown. Add URL anyway?

I hate it. I added my friend's URL so I am updated on what they are up to. So I can be updated on what is happening on their lives. So I can have a glimpse of their online journal.. and blogger will say to my face that updates will not be shown? what the!?!

If you are faced with this kind of problem, you can try changing the URL to this:

http://blogname.blogspot.com/atom.xml
or
http://blogname.blogspot.com/feeds/posts/default

you just have to add atom.xml and if won't work add feeds/posts/default instead

Don;t just love to hear more from your blogger friends?
