This is a question I've wondered for a while, and I figured this would be the right crowd for discussion!

On Twitter you've got the "big players" - the people with a ton of influence and followers. There is no "Catholic" category on "People to Follow" on Twitter so we don't have a canonical version, but who would you say are the big players in Catholicism on Twitter? I've seen some tech guys with a great follower ratios, as well as recognizable entities like the Vatican and Diocese - those stand out to me, but maybe not to the Catholic community in general.

Any ideas?
