The blog Firmuhment uses food as a metaphor in describing various websites, some of which you may be familiar with:
Twitter: A box of Crackerjacks without a prize in it.
Dooce: A peanut butter and jelly with the crusts cut off and several gin and tonics on the side, no ice.
Gawker: A stick of rock candy so hard that it breaks your teeth.
Lifehacker: A steak cooked by someone who doesn't like steak very much but is very interested in the quickest and most efficient ways to cook steak.
What, no Serious Eats? Hmmph. [via BuzzFeed]
