Here’s a look at the many facets of social media.

Last week, City Pages published an article on how Twitter may save Chris Strouth’s life. Apparently, Strouth received 19 replies to a Tweet (with a Facebook page link/explanation) asking for a kidney. Tomorrow, Scott Pakudaitis, will be lying beside Strouth at the University of Minnesota Medical Center to give him one good kidney.

On the darker side of the spectrum, Michelle Rae Wilson, charged with killing her ex-boyfriend in St. Paul, left a trail of hatred all over the web. According to the PiPress, Wilson “called her boyfriend an ‘insecure’ man who wanted to ‘stop my glow.’ She bragged online about owning several guns. She blasted harsh e-mails to friends and acquaintances, one saying, ‘Stay the (expletive) away from me b4 u get run the (expletive) down!!!!'”

Meanwhile, kcmpls tweeted a friend’s Facebook status: “My ex-husband Alex killed himself yesterday in my apartment.” What a way to tell the world. An urgent cry for help? A shout into the void?

Too much death on social media?

Let’s look at the lighter side.

According to The Deets, IKEA has made Facebook less valuable by exploiting its photo tagging functionality to promote the opening of another store. How did they do it? Easy. They encouraged Facebook users to tag themselves within photos that they don’t actually appear in, in order to win IKEA merchandise. Tag yourself in a photo of an IKEA tablecloth, and win that tablecloth. Get it? The idea is that all your Facebook friends will click through the photo to see it. An ingenious tactic, or a Facebook nono?

And with that, I leave you with this great quote.
