Hairy knuckles are gross.
Semicolons are my favorite punctuation. There really hard no hard set rules for its use. There's one thing I disagree with in the article. Using a semicolon before a conjunction is perfectly fine if the sentence is long and has a lot of information. It lets the reader stop for a second to digest what just happened while not committing yourself to a full stop.
Could you put one in an example please; I would rather stick to the good old semicolon
