I don't think it's true that bitcoiners don't like meeting face to face. There are weekly meetups (of ~10-20 people) in the city I live in - however from my personal experience with these, it's just a giant circlejerk, there's no added value from those conversations. Every meaningful discussion happens online, imho.
Well we all have fun different ways and to meet to discuss an interesting topic has no less sense than lots of other forms of entertainment. But in offline meetings most would hardly say something exact because it can be unsafe, so I guess main topics would be abstract. And anyway IMO it is good to meet, to know that bitcoin becomes more popular, etc.
