Site Demos and Reverse Teardowns

I'm always trying to think up good content that would spark discussion among our group, and I wanted to talk about the concept of site demos and reverse teardowns since they generally make great filler content and can usually initiate some good general discussions. I'd like to get some ideas for good sites to do these talk on. If you're not familiar with either of these concepts, read on, I'll explain what they are in more detail, if you have a good idea for a site to use for one of these, please post it below and we'll pick the most interesting sites to take a look at each month.

Site Demo
You've made a really cool site and you want to show the world what you did and how you did it. You can take us on a tour of the site you did, and the group will ask how you did this, or how you built that. This is a great exercise for getting some constructive feedback on your newly created sites.

Reverse Teardown
Reverse teardowns can work one of two ways, either you have access to a dev site that you can tear up, or you're examining a live site through the front end markup. Either way, you're trying to guess how a site was built. The person driving this talk should have no previous knowledge of the site, and will poke around to guess how things were built. Going off the markup gives you a basic ability to guess what's going on, and gives you no way to verify correctness, but it generally will spark some good communication. It's always nice to have access to the backend, because it gives you the ability to do a more in depth analysis, also, these types of teardowns usually have the sitebuilder in the room to verify correctness to the person driving the reverse teardown.

So if you have a site that you want to showoff, or one of interest that you'd like torn down, post here and we'll use the most interesting sites as demos and teardowns.
