Maybe they are aware enough of their history to know that they won't have a conversation. Looking through Busse's Twitter history, he has made no reasonable effort to have a conversation. If Kevin were interested in conversation, he would have read the book before inviting Busse to talk about it. You know, so he could have a conversation about it. On Rokslide, Kevin could have had a conversation about it, but he posted and ran, not bothering with attending follow-up questions.
Frankly, I am VERY good at determining who is capable of having a conversation, who REALLY wants to have a conversation and who doesn't. Anyone who asks what soul searching is, then 4 minutes later tells someone to engage in soul searching, isn't interested in conversation. Someone who uses words like this, "Too much word salad, try again, half as long." then a few minutes later accuses someone of being passive aggressive, isn't interested in conversation.
Keep up the good work. You are getting the attention you want. I am off to a Mardi Gras parade to laugh at more people.
