Very nice. The UI feels slightly slower (more sluggish) than web IRC chats. The ability to enable audio on messages or @mentions (in settings) is a good addition. But how does kwak want/expect people to use this? www.kwak.io just has 4 hashtags and jumps me straight into a chatroom. Either I am missing something or there's nothing more to this "Show HN" than literally showing it?

We haven't dig too much into optimization yet, it's _almost_ vanilla Meteor with MongoDB. The hashtags are created by the users, and they automatically rank based on activity, we will have many more interesting ranking algorithms to come.
