Content is a powerful weapon for building a community. The secret is to create content that brings people together.
Asking your community’s top 10 members to give their opinion on a topical event, and publishing the piece, brings people together.
Arranging an interview with your company’s CEO and asking the community to submit questions, brings people together.
You might also write what your members have recently achieved. Even if it's not specifically related to your community. Or write about what your members hope to achieve in the near future.
Write more about your community's members and less about your community's industry.
