Who taught you to put a comma between subject and verb?
Not generally, but the word dies can be used as a verb or a noun and adding a comma would have made it more clear. Anyway I don't want to get into a discussion about semantics.
Nope nope nope. Comma there would be unequivocally wrong. It's not a subordinate clause, not an explanatory interjection, nor a list. Commas cannot just be added randomly!
Yes, as alm correctly said to me via PM, it should be "Inventor of fuzzy logic has died, more or less." I knew there was something wrong with the thread title, but for the life of me couldn't correct it.
Well, "Inventor dies" is classic news headline style (which American TV news anchors also inexplicably use in spoken form). Nothing strange about it -- or at least, no more strange than many news headlines!
OK, this is weird. He's more or less not dead! Reload the article:
