I think the comments section is kind of undervalued and that it has a lot more value that most people think. I wrote a long article on this a little ways back called "
5 Reasons Why Comments on Your Kickstarter or Indiegogo Campaign Matter"
My main points were that comment matter because they:
1. Comments = Community
2. Building a relationship with your fanbase
3. Engagement Factors Into Ranking Algorithms (particularly indiegogo).
4. Comment section is the hub of customer service.
5. You can use comments in the future that are generated for testimonials.
I think the comments section is a good way to develop a relationship with your backers, which makes them more likely to help you out in spreading the word about your project.
