Shut Up And Let Others Speak

Craft emotionally compelling content. The kind that drives an audience to leave comments. Encourage people to share their own ideas, stories, and approaches.
Invite people to write guest posts on your blog. Find people who will add a unique perspective and who have an audience that you want to connect with – as they are likely to widely share anything they create.
Send out reader surveys. Use a service like SurveyMonkey to tap your audience for feedback, such as ideas on which problems you should tackle next. Write a follow-up post that shares some of the best ideas.
