This was actually launched January 15, 2010, but never showcased:

http://www.crucialwebhost.com

The site is primarily built using ExpressionEngine (I’d say 95 percent), at least, everything on the frontend with the exception of the order form, which uses CodeIgniter.

We also use CodeIgniter for internal stuff, like reports (earnings, signups, projections, etc.), managing cPanel/WHM servers (using an API that we developed), etc.

There are numerous APIs for EE and CI written that integrate with Twitter, a screen capture service, Nagios, URL shortner (YouURLs), eNom, Kayako, and ModernBill, and we’ll be integrating addons for Google Checkout, PayPal, and Amazon, most likely for CodeIgniter until we switch to EE 2.

The site was done entirely by myself, and took roughly 8 months to complete.

There are about 40 addons (either plugins, extensions, or modules) in use, and a majority of them were done by myself.

The site uses pure HTML5 markup and CSS3.

Feedback is appreciated, and thanks for reading!

Very nice, been reading a lot of your guys stuff pertaining to Magento also lately

@dhanshields: Thank you! Yes, we have been working heavily with Magento for over 2 years now, but are definitely looking to branch out to other applications, especially EE and CI.
