I think it's a pretty good sign that all these social media features continue to be added and I still don't see any impact on how I use Telegram.
I don't buy anything from Telegram. I don't see any ads. Yet I use its API and chat for a price of $0. Something has to give.
I know fewer than 5 people who have heard of Signal but almost all of my acquaintances have at least heard of Telegram. But nobody uses anything except WhatsApp.
LOL what?
So it makes sense that they build out more features for those use-cases like those using it as a media platform. I really like what they're doing. This is how you build a platform.
I'd be surprised if HNers are even aware of how other people use Telegram beyond basic chat. We tend to dismiss and hold disdain for use-cases we don't care about rather than learn about them earnestly.
