My take is more positive than several others here. It's a good working draft. Love the use of white space and its very easy for the eye to scan to the appropriate sections. The tone of the purple is much different and better than the garish purple used on Jancis's site.
The link to the blog should be more obvious and it would be great to list at least the titles of the three most recent posts so newbies get a better idea of the content contained therein, and go directly to it if desired.
I would like the main content background to be lighter -- not white, perhaps, but something approaching it; dark text on light background is easier to read than the reverse.
Eventually the book will not be new, maybe as early as Jan. 2009 (five months). Will you then use that space to highlight, say, a new published article -- or do you know?
Finally, if the landing page will be used to promote events and readings and media mentions, where will these listings go? Don't see a section for this type of content.
