Netiquette. "What is that strange word?" you may ask. Well, netiquette is internet etiquette, and it is an important thing to understand in this day and age. Whatever you say, even if it has been deleted, may still be lingering around on the web until the end of days. This link shares a wonderful article from Edudemic about proper Twitter etiquette. I think this is extremely important not only to educators but to the students that have Twitter accounts as well. Those angry messages and non-responses can get in the hands of a future school or employer and portray you in a light that is not all that pleasant.
