Hi Tom, great to meet you, and many thanks for all your very interesting advice. I'm still experimenting with the Grazr. It's not there at the moment - my business partner says that it looks too high tech for our audience - but it will return in some form soon.
It seems like it might make a great viral tool for promoting storynory, if we could make it nice enough for others to put on their blogs and sites, so that they have our children's stories available in their sidebars.
I noticed a bug. If you put just an RSS feed at top level, it doesn't include the very nice flash MP3 player. This works fine if it's inside a node.
I've also used Grazr as an RSS feeder on a post over at blog-relations.com, based on my bloglines subs, which can be exported as OPML.
All the best
Hugh
