Black Blade Associates (my company) has released a free tool that will let you import your Blogger blog into a SharePoint blog site. This is the tool I used to import this blog to the company SharePoint blog site. Here’s some info about the tool from the Black Blade site:

• Simple wizard-driven interface
• Supports importing from Google Blogger
• Import all or only selected posts
• Map blog authors to SharePoint users
• Imports categories
• Re-targets links to posts to target blog site
• Re-running the import won’t duplicate posts
• Supports standard SharePoint blog sites or CKS EBE-enhanced blog sites

Go to the Black Blade Blog Importer site to read more, view screenshots, and download the tool and source code.
