The document outlines 10 steps for narrowcasting on social media by focusing engagement on existing connections. It recommends researching followers' interests, engaging those who are interested, and growing the network by tracking new followers. The steps include starting with 10 minutes per day of engagement, setting goals to engage 5 new people per week initially and working up to 5 per day, using tools to create lists to organize connections, and automating reminders and schedules but not actual engagement. The overall goal is to research, engage existing connections, and leverage those connections to grow the network in a targeted way.
