+.SH RATIONALE
+
+The commands
+.BR talk (1p),
+and
+.BR write (1p),
+and
+.BR wall (1p)
+can be used effectively for textual intra-system communication, but they require
+that the receiving user(s) be both logged in and monitoring their terminal for
+any messages to ever get through. The
+.BR bulb (1)
+command was written to support asynchronous, persistent conversations between
+users of the same system. It is also possible to create bulletins, MOTDs, etc.
