Blogging 101

Yeah, so I have all these pages - yahoo 360, myspace, blackplanet, etc. So in an attempt to share my cleverness with the masses (or just generally get shit off my chest), I am trying to make it so that I can blog in one place and have it feed to the others. I think I've got it down (this is a test). Anyone who knows me knows that I am technologically challenged so if this doesn't cause the entire world wide web to disintegrate, I am grateful for any tips you can offer....
