What a great site Ian!
Interesting, informative, easy on the eye, easy to navigate. It could end up being one of those 'cult' sites that gets loads of hits even though that was never the intention.

Billie Piper has an overlap too in case you didn't know.

I only have one concern - do you have copywrite permission for all of the photos you have used? As your site is not commercial, it may not be too much of a disaster if you don't, but if your site ever goes commercial it should be a concern for you.
