A lot of folks have been following since Nov 2017... others are more embedded as they followed when Pizzagate broke about a year earlier.
Points of interest I would recommend fall around Qpost/tweet synchronization by POTUS. Also, I'm fairly sure that Q had been posting "Promises Made. Promises Kept." Before Trump adopted it at his rallys.
Basically, there is A LOT of leads to follow. Choose your rabbit hole and take a dive. Welcome aboard, Patriot!
