Leading tech experts share their expertise on Twitter
Social media has transformed the ability of those with expertise to share their views on recent events with a larger audience. Nowhere is this more true than on Twitter, which attracts millions of visits per day. Healthcare technology and IT experts are among those who frequently offer their slant on the news of the day.

This is the second effort by Health Data Management to identify HIT and technology experts who are among the most influential on Twitter. Results are ranked by the number of followers each had in early November, with our last review occurring on November 15, 2016. Of course, the number of followers can change daily on Twitter.
