Working with Tags

I've been trying to get my blogging tags sorted out so that my tags in Blogger and my tags in FeedDemon are the same.  Given that FeedDemon now synchronises with Google Reader and Blogger is now a Google product I thought it would be quite straight forward but it ain't.   There is no migration, export or import facility that I can identify so I had to print off my Blogger tags and type them into FeedDemon manually.  This strikes me as quite odd!  Perhaps Google should devote some thought to making this a bit easier
