Learn Italian: La gente diffonde il pettegolezzo, ma nessuno ne parla. - People spread the gossip, but nobody talks about it.

In Italian, the verb parlare (to talk) is followed by the preposition di when talking about something (parlare di qualcosa). The pronoun ne is used to replace di plus a noun or pronoun. Since you are replacing del pettegolezzo (about the gossip), you must use ne, which functions here to mean 'about it' or 'of it'.

English uses a plural verb for 'people', so why does la gente use the singular verb diffonde?

In Italian, la gente is a singular feminine noun. Think of it like the English word 'crowd' or 'group' — it represents a single collection of individuals. Because of this, it always takes a third-person singular verb, exactly as if you were using lei (she).

Why isn't there a non before the verb since nessuno is a negative word?

When a negative word like nessuno (nobody) comes before the verb, it acts as the subject and stands alone. You only need a double negative structure if nessuno comes after the verb. If we flipped the phrase order, it would be non ne parla nessuno.

Does pettegolezzo refer to a single piece of gossip or the general concept?
