I am trying to get together a Drupal portfolio of sorts , of truly unique "i can't believe that is Drupal" caliber sites.

I have actually seen some nice corporate Drupal sites in the past that do not feature on the site list anymore. This is nowhere near a complete list, but I think this should get the discussion going.

I would personally list the following :

I converted my site over to Drupal last month and have finally gotten around to making a theme for it, I was using the default theme for over a month. I was previously using e107. I have found that since I switched to Drupal my site traffic has gone up a bit due to better search engine indexing, page loads are faster, and publishing content is far easier than before. I post weblog entries an average of every couple days or so, before it'd often be weeks before I'd do so. The news aggregator comes in quite handy especially with its "blog it" buttons next to news items.

Cool to find one of my all time favorites is using drupal! Way to go Doc Searls.

Found on DocSearls Blog.
"You're not really live, much less alive, if you're not putting out an RSS signal. Doc Searls IT Garage http://garage.docsearls.com/ got one yesterday. Here it is. http://garage.docsearls.com/?q=node/feed

illect recordings, hip hop label, has launched their site using drupal, and a (of course) modified xtemplate.

the registration is mainly only for the press, and no discussion boards are active. we use the site to provide easy content management, a store front, and to a certain extent, internal communications between the owners (website issues, etc. using the project module).

contributed modules in use:
filestore
ecommerce
node_image
event
song

I finally got my site up and running http://www.schoolmates.com.au. Please let me know what you think. Your suggestions will help me improve it.
