That\'s one of the Tips of the Day, displayable at any time using the /tip command. Most of them are truncated.
They were cut off at some point. The reason, I assume, was to fix another visually annoying issue where the Loading... page would display a longer tip inside a widget that had scrollbar arrows, but since on the Loading screen you don\'t get a mouse cursor the arrows would be unusable and the tip truncated. It\'s also possible that the maximum length of the database column holding the tips got lowered and the tips didn\'t get rewritten - I don\'t know, didn\'t look.
Of course, this replaced one truncation issue with a different one, but still...
