check check...how does this stuff work?

Being bored at work and deciding to create a blog then realizing I have no idea what I'm doing highlights my naivete with computers and the current world of technology. It asked me "If you have burned your post feed with FeedBurner, or used another service to process your feed..." what the hell does that mean? Basically, I'm insane for signing up for yet another social site when usually I just want to go OfficeSpace on my gadgets. Wish me luck!
