Subjectively from a linguistic perspective the impression given is that most of the narrative messages from Q were written by the same person. The style, tone, diction, syntax, grammar, phrasing, construction, capitalization, spelling and punctuation, etc., would be too hard to keep ALL consistent across a large number of people IMHO.

When the drops consist of a lot of military code, links to websites, images, etc., it can be different people, hard to tell.
