You never quite know who lands on the other end. Some chats stay close to Liberia and the rest of West Africa; others jump straight to Mauritania, Senegal or somewhere on the far side of the map before you have finished saying hello.
Conversations from Liberia run in English from the first line. That makes it an easy place to start if you are new to random chat and would rather not negotiate a language barrier at the same time.
Clocks in Liberia run on UTC. Their evening — call it 8pm local — is 9pm in Berlin and 12pm in Los Angeles, which is worth a glance if you would rather catch people while they are relaxed than while they are getting ready for work.
It costs nothing, at any hour. 8pm in Liberia or the middle of the night, there is no paywall between you and the next stranger.
None at all. You do not even set a display name, and you can open the chat in English or English the moment the 18+ confirmation is ticked.
English throughout. Idioms and speed differ from one part of West Africa to the next, which tends to be the interesting part of the conversation rather than an obstacle.
Late evening tends to work best. Liberia sits at UTC, so 8pm there is 9pm on a Berlin clock and 12pm on a Los Angeles one — chats in that window usually run past the first question.
