In my opinion it's quite the oposite and I have found developers and other IT techies very easy going and forgiving. In my experience the most difficult nitpickers are Esperantists :-) Then again there are rather a lot of IT folks in the Esperanto community so perhaps the conclusion is that the difficult IT-ers are the ones who learn Esperanto and would that include me or am I exempt for I knew Esperanto before I knew anything about computers let alone programming.
