Okay, you probably don't need to hire a comedy writer. (Though maybe the tone of your daily email slog would benefit from doing so.)

But there's still an important, if simple, recruiting message in this Vulture article about Bryan Donaldson, an IT professional from Illinois whose Twitter comedy act landed him a gig writing for Late Night With Seth Meyers.

That lesson: Social media is, indeed, a recruiting tool. And that doesn't just mean LinkedIn, the network most people associate with recruiting.

Twitter and writing gigs might be well aligned from a recruiting perspective, as seen in Donaldson's example. The social network serves as a ripe opportunity for potential recruits to show off their sense of humor or wordsmithing abilities. But it can also serve as a great opportunity to find people who are passionate about an industry, and who aren't afraid to contribute to the conversation around it.

Facebook, however, might be more broadly applicable. Stephane Le Viet, the CEO of Work4, a company that helps businesses use social media to manage talent, says Facebook is an underrated place to look for talent. While LinkedIn offers a strong user base of career-minded people, Facebook, with its billion-plus members, "inherently has skin in the recruiting game," he says.

Facebook's recent innovations, like graph search, make it possible to search for people by education and the industry they work in. Meanwhile, new ad targeting options allow companies to post job listings as advertisements and make sure they wind up in the right hands.

What's more, Le Viet says, is that studies have shown that 81 percent of Facebook users want to see jobs posted there.

A story like Donaldson's looks at first glance like a fun story from the goofy entertainment industry, walled off from everyday business.

But when it comes to having a social recruiting strategy, the rest of the business world might be the butt of the joke; only 7 percent of companies boast a formal social recruiting strategy.
