Rich,
I do not use blogspot.
My thought process is, if you blog on your Artiswebsite.com (AW) page things will show up on the FAA page, because they mirror one another with respect to blogging. If your blogspot page has the ability to receive and incorporate RSS feeds, you can set it up to receive any blogs written from your AW page via RSS. This would prevent you from having to post twice.
Would that work?
Here's the screen shot from the bottom of my AW page showing the RSS options we have available at this time.
