I haven't seen him post anything since April 13 2018..or am I missin somethin?
I see the Shannon journal discussion volume 3 but not the original posting from Shannon himself about regular updates.
Yea, people use "Shannon's Journal Discussion" as "Ask Shannon Anything and Everything" instead. Makes it really difficult to have quality discussions about Shannon's journal entries, and I wouldn't be surprised if trying to read back all the latest posts saps his energy in some form, maybe results in a face palm or pinching the nose bridge or something.
He hasn't posted updates for a while. He will usually post those on his journal thread, the journal discussion thread is to either discuss that or ask him questions.
