Most importantly the Tcl'ers Chat is about Tcl. It is much like a place of business. In fact most of the people seem to use the chat from/for work. It's preferred that people not talk about personal things. Anything emotional is probably inappropriate. Most of the Internet is like this, and although it leads to a soulless feeling, it gets work done. Hence jokes are often inappropriate. Talk about Tcl. If you get upset with another person, remember that all that matters in the chat is Tcl.
If you need "friends" or want to make friends that are Tcl'ers try something else.
The chat is not a good place to discuss things like radically new improvements to Tcl/Tk. This often results in hurt feelings or flame wars. Use comp.lang.tcl for such things, because it allows a slower form of communication, and you may find more support. If you don't find support there, then do the improvements yourself and fork Tcl and/or Tk.
