It takes the sender a lot of time to type the question, so the communication is not immediate synchronous. What actually happens is that I go elsewhere after 5 seconds of waiting, then in 20 more seconds arrives the question, but I already switched to a different task and don't bother what another stupid hello I received there. The site provides a chat log with timestamps to better understand delays in communication.
