I don't use FB enough anymore to know how Trump uses it vs Obama/etc., but I'll take you at your work, mostly for the fact that I rarely (in fact, I can't think of a single time right now) have heard journalists making substantive (or even flippant) complaints about how Trump and his campaign uses FB. OTOH, most of the journalists I know, besides complaining about him, follow Trump on Twitter. Many even have his tweets get treated as Twitter Notifications.
To me the problem of Trump using Twitter is not political, but it's that he's using it for important, world-impacting communication when Twitter is inherently too reactionary of a medium for it. Both Trump and Obama have been heavily critical of North Korea. But there's a huge difference about Trump sending his thoughts via Twitter rather than speech/video address, or TV interview.
In other words, I don't believe that Trump (nor any human, president or not) is above the kind of impulsive communication that Twitter is designed for.
