the happy mania

I thought what I was going to do was take a class on Java for the fun of it. Then I started scrolling through the computer science programs offered by the community colleges, and there are certificates that could possibly mean career placement (network management, web programming etc). At this point of time I don't know if it's something I want to jump into, but it sounds like an interesting option. It also makes me wonder, in terms of job opportunities would it make more sense to go the Bachelor's route or through a vocational college providing a certificate instead? If anyone on the flist has any advice or stories, it'd be much appreciated!
