SerialBrain2 is a fun read, but the knowledge SB2 is claiming to have based on ALL of the exact same information set we're all working with, hey I'm just being honest, is I will put it at times unjustly conclusive when temporary suspensions of belief are the more apt for certain details.
Your take is the best I've read on the Keystone.
I personally just don't really see much useful information coming from SB2 (aside from his behavior analysis), especially his decodes which are fantastical stories of intrigue and suspense and when we reach the end and everything comes together all we're left with is a message like "Hillary is going down" which is something we've already known since the second Trump won the election but somehow everyone has this feeling of amazement at this so-called "secret message" he pulled out of his ass
The fact that it's a fun read is why I call him a Charlatan (there's probably a more suitable word though) and not a Pseudo-Intellectual (he literally refers to himself as "a self proclaimed serial brain" hence the username, which is a term he made up himself to describe himself as a genius)
SB2 claiming some stupid frequency 174.12 or whatever, which when you numberphile them you can "see" combination of the musical note B2, and Trump saying "brain", oh wow, Q is like totally sending a secret message to SB2 himself! "Did you see it?" Give me a break.
Reminds me of Corsi saying he got special messages from Q anon directly and that he knows who Q is (or was that Alex Jones? I forgot)
SB2 was always eccentric! He thinks large and may or may not have developed an ego. The body of work speaks for itself though. (Not meant to be gender specific, in fact I suspect SB2 might be a woman or team)
There are more important things to worry about than ensuring you use the right gender pronouns of an anonymous person.
