Many times specific dates and even times have been indicated by very complex clues, even if they turn out to be "wrong". Diving into this does a number of things, I think:
1) It serves as disinfo for the enemy.
2) It helps build an ever more nuanced understanding of the comms.
3) It more often than not leads to an understanding of additional "real" topics that are getting used in setting up some "disinfo".
Eventually, Anons who make predictions get it right, despite much "apparent" failure. And those who go and examine it all after the fact will recognize that. Disinfo is real and necessary and part of the plan. I would never have believed the things I believe now had I not reasoned them out for myself. I think things now that I would have previously regarded as crazy, but I got there by thinking.
But then there's the flip side too… how many Anons, coming at it from varied backgrounds, have put in the effort to make this happen, even though it seems "crazy" to the "real world" (which isn't real at all)? It has not been a straight line path for me, and probably not for many others too, but now I intuitively know this is the path of reality and I aim to proceed along it no matter how much I might screw up. I am literally the same person as before, but more aware. I suspect I am not alone in this.
It wasn't highly damaging to Slick Willy. I suspect he set up the whole impeachment himself, with his DS allies. They knew he would never get "convicted" for getting a BJ, and this diverted attention from all the real crimes.
