MOTD, an abbreviation standing for Message of the Day. These messages are often displayed on websites, services or different forms of communication as a means of displaying what the administrator or creator feels to be the most important and/or signifigant information to be presented since the previous MOTD.
Sometimes these messages are sent via email, and sometimes they are posted on websites as the first page that a person views when arriving. Often, these messages aren't updated, most probably due to the fact that whoever is in charge of them doesn't feel the need to change them or work on them, and sometimes simply because there is no new news or information sufficient to the creation of a new MOTD.
In fact, there have been known cases where a website or service is abandoned and, as a result, the MOTD is condemned to an eternity of inaccuracy, always being called that of the day, but never truly being that of the day beyond the day of its creation (got all that?). Such MOTDs become fallacies, and eventually are forgotten, although they may be excavated at a later date from their site of abandonment.
Due to time constraints and submission to the hand of reality, there have been services that have switched to the use of "message of the week" or "message of the month." Be this an admission of non-commitment to the daily writing of a message, or simply an experiment with uniqueness of wording, the roots of each trailblazer who attempts this always lead back to the "MOTD" from the good old days.
