Wikipedia:Comma test

Sentences should still make sense after removing their commas. This does not mean that commas are useless indeed this sentence is really hard to read without one in between the clauses. Yet the comma is one of the most abused punctuation on Wikipedia because they tolerates substandard writing and content stuffing. The comma test helps to detect overuse of apposition and passive voice which alone composes a majority of awkwardness in a Wikipedia article. The test may in some cases detect elegant variation and redundant phrases. Do use common sense when use the comma test because it won't work at all in lists and quotes.

Examples

• Taken from Venus: Solar days on Venus with a length of 117 Earth days are just about half as long as its solar year orbiting the Sun every 224.7 Earth days. The sentence makes total sense until the last clause "orbiting the Sun every 224.7 Earth days". Ditch it and the redundant "just" would give Solar days on Venus with a length of 117 Earth days are about half as long as its solar year. Chef's kiss – a delicious sentence. If you are so badly want to keep the "224.7" information here's another solution: A solar day on Venus is 117 Earth days long and its solar year is twice as long with a length of 224.7 Earth days.
• Taken from Military history: The dynamic nature of the discipline of military history is largely related to the rapidity of change the military forces and the art and science of managing them as well as the frenetic pace of technological development that had taken place during the period known as the Industrial Revolution and more recently in the nuclear and information ages. Though the comma test works poorly in lists it could still be a powerful tool in the right circumstances. In this case we can remove redundant adverbs and split the sentence into two. This is one solution to the comma test: The study of military history is dynamic due to changes in the military forces materiel and their management. Technology also play a big role in military history due to innovations spearheaded by the Industrial Revolution nuclear and information age.
