This backup tool will crawl your blog for hAtom or XOXO Blog Format content and put it all together in one file that you can save to your hard drive for backup purposes.

If you do not use the New Blogger you will have to have an archive list in your sidebar that has the class archive-list on it. With the New Blogger if you have an archive widget it should just work.

What’s that? Your blog platform doesn’t support XFN? You want more XOXO-centric markup on your blogroll? You want your friends marked up as hCards in the blogroll? Now you can!

This generator tool is based on the original XFN Creator and generates code for a full XOXO blogroll with XFN relationships and hCard nodes.

The XOXO Validator has been updated to support pages that are not well-formed XML. An XML error is displayed, but the XOXO valid message is still displayed if there is valid XOXO data on the page.

Users on the New Blogger may be pleased to discover there is a nice third-party tool for generating a profile section that is hCard-compatible!

Roger Costello has created a nice introductory S5 presentation (more on S5) for hCards.

hCards, among other things, are a building block of hAtom.
