There isn't enough love for TSV imo. Unlike commas, tabs rarely appear in input data, so you don't need complicated quoting or escaping rules. You just have tab and newline as special characters. Processing this data is extremely fast. Grepping for particular values is also very fast, as you can use the tabs as anchors when searching.

TSV allows you to do stuff on a single machine and GNU parallel that people would normally create a Hadoop cluster or 128GB database for.
