I had but found they were too generalised and go too far backwards to cover how internet messages - specifically - came to be known as "posts". So they don't discuss the evolution of the word and how it crossed over to the digital era. eg did it cross over from early shop keepers nailing physical posts outside and just became a colloquialism for advertising that way? Or was it a reference to telegraph poles (posts) used to relay messages that then because slang for transmitting messages but later become a noun - like the reverse that happened with Photoshop (noun: Adobe product) / Photoshop (adjective: edit an image).
