Well, Shakespeare quotes every day and Chaucer doth tweet, so what about Pope? Not Pontifex, he seems to have an account but to be silent.
I was prompted to start this by seeing Jeremy Hardy last night. Clydesdale and I agreed that his rants, or material, were / was much the same as mine but that he was much nicer and funnier - and he's on Radio4.
I tweeted him to this effect but then softened it to "What oft was thought but ne'er so well expressed." That was Pope (not Pontifex). Still no tweets from him or Himself, or replies from anybody (except my one loyal reader), in fact.
