I just visited the chat room and it is so complicated.
Can anyone explain me what is happening there?
Why do I see so many
Why isn't this simple like other chats?
Is it only technical chat happening?
Let me see if I can address these elements:
Our chatrooms allow you to paste StackOverflow links and directly display a preview of a question, answer, tag or user. It's what Faheem did, you can see the title and body of the question, together with Mike's picture and the number of votes this question received until now.
Update: Joseph also pointed out that certain sites are also "expandable", like a Wikipedia article, an Amazon product and others.
This is some sort of dropdown menu, if you click it, it will expand to this one:
Regarding item 3, if you or somebody else liked the message and marked it as interesting, you'll see:
All those three icons are shortcuts to the dropdown menu we saw earlier.
If someone stars a message, it will appear in the right column of the chat. If you see a number right after a star, it represents how many people starred it.
Yellow stars represent the ones you marked as interesting.
This arrow means that, e.g., Martin replied to one of Joseph's messages. You can use the reply action in the dropdown menu or use the shortcut. You can also use
@username to call his/her attention.
Update: Joseph also pointed out that the arrows help you to follow the discussion thread.
