Never say anything on Twitter you wouldn’t want people to find out about, or wouldn’t say in any other situation.
One of the best ways to connect with students and other academics on Twitter is by asking open-ended questions in your feed.
Twitter already forces you to be succinct, but you should keep things under the limit for a reason: when you shorten your tweets, it leaves room for others to chime in and retweet.
Tweet regularly. Twitter isn’t going to do you much good if you don’t ever use it. Develop a regular tweeting schedule both for yourself and for your courses that use Twitter.
