How to Use the Blogger API

Cleaning out my email, I noticed a message from February 2002 in which I had included Meg's link on how she used the Blogger API.

I have no clue yet as to why I'd use the Blogger API, but I thought it would make a good reference. If anyone has already implemented it - other than Meg, of course - let me know. I don't understand how or why it would be beneficial, so let me know what you think.
