In all of my years messing with computers, I have met very few people who are as fluent with the technology and the terminology. There is virtually no one I know that I can talk to about the things I do. I do not work in IT. I do not know people in IT. I also do not go out of my way to find IT folks. For a while this bothered me a little.
On pondering this, I suppose everyone with a hobby has this same lacking. For that matter, anyone with a mind that contains unique thoughts has the the same lacking. A desire for comradery seems pretty universal.
That said, not being able to talk about it and not being allowed to talk about it is quite different!
