Since you asked, as Q has explained many times, coincidences specifically are the method and the medium of Q's intelligence drops. Only in this way can classified intelligence be imparted without legal repercussions. That's why Q followers avidly look for such coincidences in his posts like the repetition of the letter 17, "accidental" insertions of the letter Q, happenstances whereby events happen on the exact date or time 30 days, or a year, into the future, etc. This isn't about numerology, it is a new language taught by Q that enables us to receive information that would otherwise be classified. The coincidences are placed before us almost daily to establish trust, as it long ago became mathematically impossible for this many coincidences to be just coincidental.
