Is lurking a healthy trend?

[Mike Smith]

Don't worry, if someone was really out to get you, they'd have you already

And when you're on a mac, or pretty much any non windows pc, you're guaranteed security, through obscurity of course.

Not to make the windows users scared, as I'm one of them, just make sure you got at least a software firewall running (Windows XP has one built-in) and if you have a hardware firewall, which is bound to almost every router made these days, then you're pretty safe in that way too.
