How would you create a PLN prior to engaging in a social media campaign on a topic of your choice?

Social media is a great resource for connecting with people around the world and it can also be a great resource for learning about your city or community.
Before participating in a social media campaign, I would choose a topic that interests me or is a popular topic for recent social media campaigns, such as food and entertainment. I will take photos of the surroundings and dishes as I explore a new restaurant to try their dishes and will post my food sharing posts on my social media accounts. But before I do so, I will look at how other bloggers on social media networks edit the text of their food blogs to get an idea of how to write a good post.
In addition, I would add my own personal style to my posts to attract people to read my blog and get interested of it, which also makes the readers to remember my style of content.
