Blogger.com introduced custom permalink feature...
Blogger.com's New Custom Permalink
Custom Permalink On Blogger Blog
Blogger.com had just rolled out a new way of making your post with the Custom URL feature.
As you may have noticed it, this very blog is a blogspot blog. Earlier when creating a post before this post, I have noticed that the people from blogger just gave us a power to make a custom URL on each post.
This is really a good news to all bloggers on Blogger.com, before this, you can only find this on a self hosted blogs.
Doing this is only self explanatory, just select the "Custom URL" radio button and a textbox will appear where you can put your custom URL.
Whew! there's still a surprise, the custom permalink is case sensitive, nice!
