### Explanation
It’s a basic and a most obvious pattern of functionality implemented not only in social media platforms in format of chats, but in public posts and similar entities also. For example, X (former Twitter) has both public and private communications functionality implemented with replies to tweets and messages.
Also, for some social media this type of functionality could be secondary, increasing engaging of an audience, e.g. built-in public chats like in Twitch implemented with IRC protocol.
### Examples
- private chats in messengers and social media
- posts in microblogs and imageboards
- emails (private, email lists)
- [Messages in Twitch](https://blog.synoslabs.com/osint/2022/12/06/osint-on-twitch.html#messages)
