No. It is only used by certain groups. It is not used as a public space in conveying news of a general nature. You can see the order of app usage worldwide, maybe Discord isn't in the top 10.
You have to judge the application based on usage for the crypto space because if it is for the public space then the position of the telegram application is not in the top 10, the discord application may be in second place after telegram for the use of chat crypto communities around the world.
yes, we don't need to compare applications for public spaces because there are many types of chat applications but we have to compare with applications for use in crypto space, telegram and discord applications that are popular for that and both have different features.
