Little heads-up: most probably tomorrow we'll be introducing replies to comments. Meaning, if a user replies to a comment that comment would be shown in its own sub-thread (reply to a reply would still sit in the same sub-thread). As mentioned in several previous posts, it's bit of a challenge to transition from one state to another, so I'm asking for your understanding.
The app is also ready for production release with this feature, but before everyone updates their apps, some comments might look bit confusing.
Ultimately, long threads should be much easier to follow, maybe even with an option to mute certain sub-threads? We'll see how this feature evolves.
Happy to answer any questions on this.
