Launching v4 was the chance for Digg to return to their rightful place. They implemented write-through-cache Memcached through Cassandra bottleneck. However, MyNews page was still broken every 4 hours. To keep the site running, rewriting is needed.
Where Does the Energy of a Good Strategy Come From?
The key to an effective strategy lies in channeling limited energy into the points that can generate the most impact. Common sources include: leverage; proximate objectives; chain-link systems; design; focus strategy; growth; advantage; external change; inertia.
The Core of a Good Strategy: Coherent Actions
Coherent and complementary actions refer to actions that directly support each other to create synergy; strategic collaboration can be designed and is centrally imposed on the system; centralization has its pros and cons, as the interests of various sub-organizations differ; organizational collaboration is time-consuming and labor-intensive, aiming for maximum efficiency and just the right coordination as the outcome.
The Core of a Good Strategy

The Advantages and Disadvantages Change with Perspective
Things themselves are neither good nor bad; it all depends on people's thoughts. Just like the legend of David and Goliath, the story of Walmart defeating Kmart, and Andy Marshall's strategy against the Soviet Union during the Cold War arms race, advantages and disadvantages can be transformed. When we discover our shortcomings, instead of feeling frustrated, we should change our perspective and approach.
A Good Strategy is Unexpected
A good strategy is both surprising and reasonable. For example, in 1997, Steve Jobs' turnaround strategy upon returning to Apple involved drastically reducing the product line and focusing on a few profitable products. Trying to do everything and believing everything is important is equivalent to believing that nothing is important. Good leaders need to know not only what to do but also what not to do.
