The Pushbullet app has gained significant engagement on its subreddit, with over 1,400 active users who contribute to the community and provide support for the company. The founder, Ryan Oldenburg, attributes this success to the fact that Reddit's existing culture allows users to take ownership of the forum, reducing the need for moderation and creating a more organic experience. Pushbullet's decision to host its user support on Reddit rather than its own website has been a key factor in its success, allowing the company to tap into Reddit's existing community and leverage their passion and expertise to provide better customer support. The subreddit has become an essential channel for the company to engage with users, gather feedback, and share updates, making it a valuable asset for Pushbullet's growth and development.
