A sharticle is a blog or web article filled with material less entertaining than a loud noisy release of fecal matter. People might say, "Come here and look at this", but they soon will be bored with the lack of information or the rank presentation thereof.
Used in a sentence:
Amy's sharticle on her dad liking My Little Pony at Yahoo Contributor's Network was super annoying. I wouldn't even read it while having a shit.
