If a blog is like a rock that you wipe your tears away with, then the links to other blogs are just the resulting abrasions.
If blogging is like going to the gym, then the insipid content is like the fat -- fat that is more pounds than an armored truck accumulating money underwater. A British armored truck with pounds inside. The currency. I think.
If clumsy similes are like overwrought, over-the-top Meatloaf songs, then metaphors are like the creepy David Finches that leave in footage of Meatloaf's pants falling down while he's running in Fight Club.
