The document provides 3 ways for bloggers to grow their blog with groups: 1) Start a blog carnival where bloggers write on a monthly topic and share each other's posts. Consistency is key. 2) Form a critique/mastermind group of 5-7 bloggers who give feedback on draft posts using a checklist. This improves writing quality before publishing. 3) Organize blogger meetups on Meetup.com to find others and potentially create your own meetup group to build community. Working with others through groups engages more readers and supports bloggers.
