Possible disadvantages

• Cost
  While it offers free plans, some advanced features and higher usage limits are behind a paywall, which might not be economical for all users.
• Learning Curve
  The wide array of customization and features could present a steep learning curve for new users not familiar with comment management systems.
• Dependency on External Service
  Relying on a third-party service may introduce risk, as changes or outages in FastComments can impact the commenting system on your site.
• Data Privacy Concerns
  Users and site owners may have concerns regarding data privacy and how user comments and data are handled by a third-party service.
• Limited Offline Support
  Since it is primarily an online service, there may be limitations in accessing or managing comments when offline.

• Focused Learning Tool
  Based on the name suggesting a 'dojo' for diffs, it likely provides a specialized, focused environment for practicing and understanding code differences, which can be valuable for developers looking to sharpen specific skills like code review or version control comprehension.
• Practical Skill Building
  Tools with a 'dojo' branding typically emphasize hands-on practice, which can help users build practical, applicable skills through repetition and real-world scenarios rather than just theoretical knowledge.
• Niche Specialization
  By focusing specifically on diffs, the platform may offer deeper, more targeted training in this particular area compared to general coding platforms that cover many topics superficially.
• Potential for Gamification
  Dojo-style platforms often incorporate gamification elements like levels, challenges, or achievements, which can make learning more engaging and motivating for users.
• Community Learning Environment
  Such specialized platforms may foster a community of like-minded developers focused on the same skill set, potentially leading to peer learning and shared resources.

  Another one I can recommend enthusiastically but forgot to mention before, is a paid service called FastComments (https://fastcomments.com/). Great, non-heavy code with a super-helpful developer. Source: over 4 years ago
