I want to get a reality check because from what I see on here, it seems like only a handful languages are ever discussed. I don't work in either language professionally and I feel I'm missing out on major career opportunities.

I understand the reasons why Java/C# don't get discussed too much, I just want to know how many of us use it.

Thank you.

EDIT: Thank you for the responses so far, it seems that I am indeed throwing away a lot of career opportunities.

As an aside, for the Java stack, is learning Core Java , Servlets / JSP, Hibernate (or other ORM) enough to meet the basic skills required for most of these jobs?
