I have seen a number of people create read-only Telegram channels — that they post to, and their audience only reads from, and can comment to their posts.
It feels a lot like a micro-blogging profile.
Except that the presentation is different —
• Telegram doesn't have a concept of a home-feed, that would mix posts from different channels together,
• instead, the channel is a unit, and you see which channels have new posts (and how many are unread by you).
