do I need SELinux?

[nicholas manojlovic]

Installing FC3 for desktop purposes (surfing the net, email, programming
enthusiasm etc) - I have virtually no understanding of SELinux and how
it is applied. Do I want it? Do I need it? Would I be better off without
it? 

Im fairly sure Im not the targetted audience, but Ive always viewed
Fedora as being a fairly well-suited desktop machine - obviously they've
included it for a reason.

Any thoughts?
