"Q significance?"

The purpose of this question is unclear.

If asking generically about Scavinos relevance and his social media posts relevance to Q, consider doing a key word search of Q drops for references to Dan.

As Q told anons many times, "learn our comms" so kudos for expressing curiosity which can lead to learning if that curiosity is matched by the willingness to expend some time and energy to find out.

Bon voyage. 😘
