This is what you build to juggle 6,000 tweets a second. That's the headline that caught my eye and it's about the challenges of Twitter and the data that they handle.

They also have lots of unstructured data (photo/video) that is combined with more traditional, structured data. They've used a few different database platforms to store this data and assemble it with their application. That's the same things that most of us also do when we deal with many different types of data.
