That's what happened to me whilst I was mucking about with tech support --- the world changed, C and Assembler went out of style, and everything went to the web and OOP.
And the world is changing on us yet again, Jen ... I think this Rapid Application Development thing is going places. Ruby on Rails is all the rage here in Austin.
I've been considering taking a Java course at the community college.
The nice thing about Java is that it makes C# a cinch, and vie versa. So learn one and you more or less get the other free.
Do you use Eclipse? It took me a while but it's my Java IDE of choice now.
