…isn’t a great reason to build a community.
1) What will draw people to a community in the first place?
2) By nature, you’re drawing people in and then sending them elsewhere to talk about you.
3) There’s no obvious reason for anyone to do 1) or 2).
Community isn’t a great approach for ‘getting the word out’. There’s plenty of advocacy, influencer, and promotional efforts that work better.
Communities can help in some areas (once they’re established). They’re terrific places to source case studies, testimonials, and referrals. They’re fantastic for creating social proof and enticing those with an interest in whatever you do to take the next step.
But for just getting the word out? I’d consider a different approach.
