Those who use their Twitter accounts for both personal and professional purposes often find themselves wondering whether they are damaging their credibility with funny anecdotes or social tweets. According to a study published in the March issue of Learning, Media and Technology, however, the answer to that question is a resounding "no."

Instead, students perceive instructors who make social tweets as more credible than instructors who remain strictly business, lending support to the idea that knowing a real human is behind the Twitter stream helps people feel more confident about that person's abilities.
