Alright, seeing as nothing interesting has happened yet, I'll lay down my reasoning.
It's a Day 0. Mafia may or may not know each other today (I didn't check to confirm this in the rules). This is mainly for feeling players out.
A no-lynch is what's on everybody's mind, and it benefits both parties, though mafia especially enjoy going a free day unchecked. It sets their kills up (ex: which players are acting shifty, etc.) and they generally don't get any suspicion.
We need everyone to check in and be active before a no-lynch becomes a priority.
