Reactions are the like button widened into an emoji palette: hearts, fire, laughter, anger. Facebook mainstreamed them; Telegram made them the visible applause of channels, where the emoji row under a post is often the only public engagement it shows.
One button collects one bit of information. A palette collects sentiment: loved it, laughed, angry, sad. For ranking systems that's richer signal; for users it makes reacting possible where a bare like feels wrong, like bad news.
The cost stays one tap, so reactions inherit the like's role as entry-level engagement with a little more meaning attached.
Telegram channels have no public comments by default, so the reaction row carries the whole visible response. A post with healthy views and a silent reaction row reads as broadcast into nothing.
That's why Telegram reactions exist as a product beside views: the row is the applause, and advertisers glance at it right after the view ratio. Premium reactions add a paid layer on top in Telegram's own economy.
Enable a curated reaction set that fits the channel's tone, watch which reactions posts actually earn (sentiment data in miniature), and keep the row proportional to views if you top it up: applause louder than the audience reads exactly as what it is.
Same family, same one-tap cost. Reactions just carry a flavour. Ranking systems treat them as light engagement signals either way.
Common and fixable: enable reactions if they're off, ask occasionally, and remember passive reading is Telegram's default culture. If the gap is extreme, the reaction row can be topped up into believable proportion.
On Telegram there's no feed to hurt: reactions are social information. On Facebook, angry reactions are still engagement, and the platform has tuned their ranking weight repeatedly over the years.
