Value investing is easy. It's cheap, low risk, incredibly effective, and the preferred stock-picking method for some of the investing world's biggest names, including Seth Klarman, Bill Miller, Bruce Berkowitz, and of course Warren Buffett.

I heartily recommend a value strategy if you're aiming for low-risk returns while investing in individual stocks. But if you're willing to embrace turbulence in exchange for a shot at sustained, long-term gains at or near venture capital's 20% annualized, you'll have to look up from the spreadsheets and Securities and Exchange Commission filings.

You'll have to think bigger. You'll have to invest like a venture capitalist. This is what we do at Motley Fool Rule Breakers, and it's earned us the top spot among investing newsletters ranked by the Hulbert Financial Digest with a 14.8% average annual return over the past five years, roughly 11 points a year better than the overall market.

How venture capitalists inspire me
A few weeks ago, my friend and Rule Breakers teammate Rick Munarriz offered up three strategies for earning high returns over time. Today, it's my turn to chime in, but instead of giving you strategies, I'm going to touch on three themes that I think are investment-worthy.

If you've read much of my recent coverage, you know that I'm a big believer in the sort of thematic investing that characterizes venture capital. Here's a look at what's been on my mind lately:

  • I'm following Boingo Wireless (Nasdaq: WIFI) because I believe that existing telecom networks will be unable to handle an exponential rise in data traffic.
  • I'm following soon-to-be-public HomeAway because I believe timesharing has outlived its usefulness for vacationing families that prize flexibility.
  • I'm following Facebook because I believe there's a war brewing over how software should be developed. Nothing less than the future of well-known computer operating systems is at stake.

My approach is to look for patterns of disruption and then invest as early as possible, knowing that the early investor is most likely to realize the greatest long-term returns when the intent is to hold for an extended period of time (a decade or more, in some cases).

Where the volcanoes are
I particularly like all three of the opportunities you see above, but I also think of them as low-hanging fruit. Each company is well-known if a little misunderstood. The opportunities they're tapping into are well-defined and should help to produce outsized returns for today's investors. You might even see one or more of these businesses appear on our Rule Breakers scorecard.

But I promised you more than low-hanging fruit. I promised Big Ideas. Here are three I'm looking at right now:

1. Social commerce
Sometimes we call it word of mouth. Other times we call it authentic marketing or even permission marketing. Whatever you want to name it, testimonials are the most powerful form of marketing. Yahoo! (Nasdaq: YHOO) coined the term social commerce in 2005 to describe the idea of using social media to help distribute testimonials, but I think we're past the point where tweeting user ratings is novel.

But that doesn't mean the idea of social commerce is dead. Imagine a Facebook group created solely for the purpose of seeing a certain film or finding the best organic food deals. Wouldn't retailers, producers, etc. want to engage with that group? What mechanisms would they use? How would couponing work? Facebook may very well be the best tool for these ad-hoc gatherings, but if consumers' loathing of broad-based TV advertising is any indicator, the overall marketing process is ripe for further disruption.

2. Content independence
This one's obvious, right? Consumers and businesses alike are increasingly drawing content from different sources, whether the content is work or entertainment themed. We can blame the rise of mobile apps and cloud computing for the shift.

Consider Dropbox and Box.net. These services are really nothing more than online storage closets. But using them gives consumers and business users the flexibility to work from a variety of devices and operating systems. I've begun documents on my Android tab that I went on to finish on my Mac laptop.

Similarly, Netflix (Nasdaq: NFLX) has created apps for a variety of platforms while handling streaming synchronicity via its cloud-based servers. Start a movie on an iPhone and finish it using the Wii connected to the living room TV? It's not only possible, it happens all the time.

As an investor, I'm betting this "Netflix effect" will become common and that Google (Nasdaq: GOOG) with Docs, Google TV, Google Books, and YouTube will lead the effort to bring cloud synchronicity for every type and style of content, making devices nothing but small servers. Facebook also has an interest in enabling this shift.

3. Clean skies
Airlines are awful businesses. As an investor you could gripe about any number of things: inept management, ludicrous labor strife, weather, massive capital requirements, and so on. But all these issues are dwarfed by the perpetual problem of fuel. Rising oil prices always lead to sinking airline profits.

Fortunately, some innovators are beginning to take action. Privately held biofuel manufacturer Solena Fuels came away from the Paris Air Show with tentative agreements to supply some of the nation's largest carriers, including AMR Corp.'s (NYSE: AMR) American Airlines and United Continental Holdings (NYSE: UAL). Boeing has also demonstrated a willingness to manufacture biofuel-ready jets.

But there's a huge difference between goodwill gestures meant to appease the green movement and building a value chain capable of delivering millions of gallons of aircraft biofuel. Producers capable of scaling up to meet demand are required, a role that newly public Solazyme (Nasdaq: SZYM) may be equipped to help fill.

So those are my three ideas. What big innovations are you betting on now? What industries would you like to see change, and how would you change them? Please weigh in using the comments box below.
