Is Social Media Dead as an Investment?

Investors are fleeing social media stocks in droves. Pandora (P), Groupon (GRPN), Zynga (ZNGA) and Facebook (FB) are all being crushed. Angie’s List (ANGI) and Yelp (YELP) aren’t doing much better. Only LinkedIn (LNKD) is trading around where it was on the day of its IPO. Does this mean the end of the game for this sector of the Internet 2.0, or is it just a bump in the road? While I don’t have a horse in the game, I’ve come out publicly against owning any of these stocks. What do you think?
