> It is highly unlikely Trump could build a platform or co-opt one that has the reach of Twitter.

Thought experiment: if instead of posting on Twitter, he sent an e-mail to a few thousand journalists?

I never use or consume Twitter, but I see screen captures of things Twitter posts all the time.

Granted: one big thing this approach misses is the back and forth. I gather Trump re-tweets quite a bit of stuff, and responds to others. I guess that could be simulated via e-mail.

My point is that as far as his ability to be heard, I don't think Twitter is necessary.
