Convenient but poor UI Easy to get a lot of people to use from different platforms such as from iOS to Android to windows. However  Lots of wasted space   compared to IRC  chat rooms take up almost four times as much space  requiring a lot of scrolling. Picking a chat room or a private message is difficult because they're all grouped together and the order constantly shifts since it's sorted by last sent message. Security implementation is also less-than-ideal  requiring you to trust telegram to not read your messages.
