Joe Stump, Lead Architect at Digg, gave this presentation at the Web 2.0 Expo. I couldn't find the actual presentation, but fortunately Kris Jordan took some great notes. That's how key moments in history are accidentally captured forever. Joe was also kind enough to respond to my email questions with a phone call.

Sounds like we need a new approach

Basically, IE6 users are forced to use IE6 at work. Giving them a message saying, “Hey! Upgrade!” in this case is not only pointless; it’s sadistic.

Diggin blogi toteaa tutkimuksensa perusteella, ettei kaksi kolmesta IE6-käyttäjistä yksinkertaisesti voi päivittää. "Giving them a message saying, “Hey! Upgrade!” in this case is not only pointless; it’s sadistic."

July 2009 Survey at Digg shows that over 90% IE6 visitors can't, won't, or are forbidden to upgrade their browser.

I was surfing website and searching for inspirations and I stumbled upon digg.com. I discovered a small utility on every single post, the share link. Yes, I want to implement that, it looks cool, practical and useful! So, this tute, we are going to make a digg-style post sharing toolbox. It's all pretty straight forward and need a little bit of planning. The way it works is different with digg's. If you view the html source code of Digg's, it has the sharebox html code in every single post. But, in this tutorial we have only one sharebox, and all the links are sharing the same template.

answer is 3TB database???

"The fundamental problem is endemic to the relational database mindset, which places the burden of computation on reads rather than writes."

Wow, cassandra uses a lot of disk space. Trade offs!

technical tools

While having great content and an appropriate message are crucial for success on social media news sites, having a quality user help with promotion is essential to build momentum

It is easy to forget that the big popular sites were once small too. The first version of Digg cost $200 to build and launch. After Kevin Rose came up with the idea back in 2004 he found Owen Byrne through eLance to develop the idea. He was paying $99/month for webhosting and got the domain name for $1,200. A few months later he launched the site with an announcement on his blog. This is what it looked like.

Social Media Marketing is Easy-

The importance of establishing a strong social media presence has been discussed to exhaustion. You know that you need to be an active user on these sites because social media can produce numerous benefits for you and your brand. Of course, as the bandwagon for social media has filled up, many myths have been spread.

# # Scaling practices turn a relational database into a non-relational database. To scale at Digg they followed a set of practices very similar to those used at eBay. No joins, no foreign key constraints (to scale writes), primary key look-ups only, limited range queries, and joins were done in memory. When implementing the comment feature a 4,000 percent increase in performance was created by sorting in PHP instead of MySQL. All this effort required to make a relational database scale basically meant you were using a non-relational database anyway. So why not just use a non-relational database from the start?

As Digg started out with a MySQL oriented architecture and has recently been moving full speed to Cassandra, his observations on some of their lessons learned and the motivation for the move are especially valuable. Here are some of the key takeaways you find useful:

HOW TO: Get the Most Out of Digg

46% of the Digg Front Page is Controlled by 50 Websites

Recent changes and restrictions made by Digg.com to encourage diversity in the range of users whose submissions reach the front page have had 2 profound results. Newer and less active users have seen their stories reach the front page, but the sources that are able to hit the front page have tightened.

"Despite tens of thousands of submissions every week, the last seven days have shown that 46.6% of the Digg front page comes from 50 websites, according to data accumulated on di66.net."

Some of us know what hitting the front page of Digg can do: send 20,000 - 200,000+ clicks through to a site. Some of us have even felt the blessing (or curse, depending on how you look at it) of the Digg Effect. But how much do you know about integrating social media, specifically Digg, into your site, and what the benefits of doing so can bring to publishers?
