Complaint buster for healthcare thanks to Social Media: let's dream for a moment #health20fr

Some hotels are apparently starting to use Twitter to identify and fix their guests' problems. 

 Increasingly online "e"-services and platforms have a community manager to answer Tweeps who shout out a problem 24/7.

So, let's dream a bit about health care...Who has tweeted about a healthcare problem and gotten assistance from anyone other than a consumer, patient, or friend? I'd like to hear from you, if you have. Will it be different in the future? Maybe...Of course, there's a tremendous hiccup, which is confidentiality...but there may be subjects for which confidentiality would not be problematic.
