Conclusion from the abstract:

Many graduating pharmacy students use social media; however, there appears to be a growing awareness of the importance of presenting a more professional image online as they near graduation and begin seeking employment as pharmacists.

Anecdotally, I can say the same for medical students. The vast majority of my classmates seem to change their Facebook name to some weird alias when residency interview season rolls around. However, as someone who has worked hard to cultivate a positive online presence and never been asked about it in an interview, I truly wonder how many programs are looking at candidates online.
