Show off your Drupal site

I'm not sure if this is bad etiquette, but I'm really impressed with a site and would love to try and copy it...not so much in terms of design, but in terms of functionality. (I need to create a catalog type site for the company I work for.) Can anyone identify the modules they've used? Or do you guys think it's simply a heavily modified instance of Drupal?

The site is... www.fiel.com

Thanks you for any assistance.

Earlier this year, I was asked to help the MiNa Group at The University of British Columbia put together a Drupal site to serve as a technology showcase and resource catalog for the group. Here's what we came up with:

Hello, I would like to present a new site (not really finished yet), "Sharing Blogs".
url: http://www.sharingblogs.com.

Well, like its name says, the basic idea is to let people submit their feeds (using FeedApi Module, users can submit their OPML files).

All the users can vote all the submitted blogs, I think that this is a nice way to know new good blogs :).

The theme i used, is a really small modified version of the Whitejazz module.

Other modules that I used:

Is drupal good enough for large scale content portals?
Do you think a site like CNN could use it?
Consider these issues in your answer:

1) Performance under heavy traffic (let's say 500,000 users/day)
2) Scalability - multiple servers
3) Security
4) Development/design flexability

Thanks.

Just today i started this website. hope you like its color combination.
