To those who are grumpy about people staying on Twitter, I just want to point out that there are chat curators who have built large followings over many years for niche topics like cancer (#Curetoday) health it (#HITSM), healthcare management (#HCLDR), etc.
To leave Twitter is to risk losing 90% of their followers and impact, and casting patients, carers, researchers, clinicians, etc adrift
It isn't just that easy, and it's a crappy dilemma
