Hi
I've just upgraded my website to 4.6, and done a big redesign in the process. The site is http://www.flyingstartups.com, and is a community to support the entrepreneurial readers of my books on starting a business.
My books all have a plug for drupal in them by the way, including the website address, and you can see them listed here:

In redesigning the site I must thank Chris Messina for his fantastic Civicspace and Democratica themes. I've kind of hacked them both together to create my theme. They look great, and the special admin theme is inspired. It makes admin so much easier somehow.
There's been some fantastic dev work going on in the last year and, as an observer from the sidelines, I think drupal has made a quantum leap in usability, stability and flexibility in that period. The range and quality of add on modules is impressive, and I will gradually be adding these to my site to expand the service I provide. In particular: the ecommerce modules, trip search, simple_access, subscription, weblink and workspace . And of course just because they've been around for ages we shouldn't forget the gifts to site admins that are: image, img_assist and flexinode.
Thanks to all of the core development team, the module and theme developers, and to the rest of the community for making drupal so great.
