The first time you use Secure Scuttlebutt will be boring because it will be an empty town, you will not have anything and you will not see anyone's feed either. The magic happens when you start following someone or you are at the same network as someone else your client start downloading the log of your friend and the log your friend have stored from their friends, and the feed is filled with information. You will even be able to view your social network offline and you will even be able to do comments in other peoples feeds and it will sync when you are online again.
Most likley you will not be on the same network as anyone else which means you will not be able to see anyone so the solution is to walk in to a pub where almost everyone in the town are
You will find a list of public pubs which can be used in Patchwork to access other feeds https://github.com/ssbc/scuttlebot/wiki/Pub-Servers
What the Pub solve is that you can download a bunch of peoples feed without they and their friends have to be online.
