I've recently changed jobs to a company that uses both .NET and Java. My hobby (if one looks at my profile it's blindingly obvious) is Python.
I've asked, and answered, many questions in the .NET and Python tagged questions.
Since changing to my new job, I've had a couple of occasions to search for issues related to Java.
In these cases you either have a few answers that end out not working, and then it seems like interest just... tapers off.
Do I just have some sort of bias here, is this just "how the Java community is", or is StackOverflow just having trouble attracting the right kind of Java developers?
