Today we are adding native support for comments in channels. So once you update Telegram, you’ll be able to leave comments in some channels, including this one.
Throughout the next 10 days I’ll be posting stuff here to try this feature out.
What I like about our implementation of comments is that they are indistinguishable from a group chat. In fact, all comments in a channel are hosted in a group attached to that channel.
This allows for many possibilities both for commenters (e.g. adding voice messages, stickers, GIFs etc. to comments) and for admins (e.g. limiting voice messages, stickers, GIFs etc. in comments).
