I have not. While I am intrigued with the possibility of making online income, it seems to be less passive then how I want to spend my time. Regarding your blog / site, you have done quite well for yourself. However, you have to keep pumping out content or your site would eventually go out of business. That sounds like more of a commitment then I would want. Regarding your book sales, it is probably relatively passive now, but certainly was not when you were writing the book. Now if you love it, great. Just not for me.
Why did P2P lending get a liquidity ranking of 6? It is quite possibly the most illiquid investment option you listed. You said you rank liquidity by “difficulty level of withdrawing your money without a massive penalty”, and for Lending Club notes, it’s not only difficult and extremely time consuming to sell all of your notes in their super illiquid market, but you would have to sell your notes at large losses to hope to get others interested in buying your notes. On top of that, it is impossible to withdraw your money any other way other than just waiting for interest/principal to pay off every month until maturity in 3 to 5 years. You can’t just one day tell Lending Club “I want to quit, please give me my money back.” One can even argue that it is less difficult to sell a home (in order to “withdraw” the money invested) than to withdraw all of their money from a P2P loan portfolio because it is very possible to sell a home before 3 to 5 years.

I live in NYC where I never thought buying rental property would be possible, but am looking into buying rental property in the Midwest where it cash flows and have someone manage it for me (turnkey real estate investing I guess some would call it). I agree with what Mike said about leverage and tax advantages, but I’m still a newbie to real estate investing so I can’t so how it will go. I have a very small amount in P2P…I’m at around 6.3% It’s okay but I don’t know how liquid it is and it still is relatively new…I’d prefer investing in the stock market.
eBay Store: It’s now easier than ever to run an online eBay store. You can, of course, acquire products to resell on eBay. But you can also create an online store to market products that others are selling on eBay and share in the commissions generated by the sales. Recently I interviewed a family friend who started her own eBay store and now makes five figures from home. Check out the interview here.

Wouldn't it be nice to earn income without worrying about it? I'm not talking about doing your regular 9-to-5 job, but through passive income. Because, believe it or not, there are several easy ways to earn passive income. Yes, some of the ways may involve some work, time, and money up front, but once that's taken care of, you can sit back and watch your bank balance grow.

A normal distribution (bell curve) is the limit of what one would find by adding up the value of many independent quantities such as the height of people in a large group. A power law distribution is the limit of what one would find by multiplying the value of many independent quantities such as the relative size of forest fires over a large enough area and a long enough period of time.
What I’m doing: My realistic goal is to have a blended annual return of 2x the risk free rate. With a current 5% hurdle, I am not paying down mortgages that cost less than 4%. Debt at 5% is a wash. My realistic blue sky scenario is a 3-4X rate of return over the risk free rate which can be achieved with property, stocks so far for the past five years, and certain private equity investments. Where I am dragging is my blended average CD interest rate of roughly 3% from an old CD coming due. I’ve rolled some money into a 12-month CD with CIT Bank at 2.5%. It’s the best rate I can find.

The growth in the IT sector is attributed to increased specialisation, and an availability of a large pool of low-cost, highly skilled, fluent English-speaking workers – matched by increased demand from foreign consumers interested in India's service exports, or looking to outsource their operations. The share of the Indian IT industry in the country's GDP increased from 4.8% in 2005–06 to 7% in 2008.[214] In 2009, seven Indian firms were listed among the top 15 technology outsourcing companies in the world.[215]
India's gross national income per capita had experienced high growth rates since 2002. It tripled from ₹19,040 in 2002–03 to ₹53,331 in 2010–11, averaging 13.7% growth each of these eight years, with peak growth of 15.6% in 2010–11.[328] However growth in the inflation-adjusted per-capita income of the nation slowed to 5.6% in 2010–11, down from 6.4% in the previous year. These consumption levels are on an individual basis.[329] The average family income in India was $6,671 per household in 2011.[330]
Portfolio income can come from multiple sources – interest/bond coupons, stock dividends, financial strategies including derivatives and capital growth.  Each offers some cash flow and some also offer potential capital gain with some risk from liquidity and volatile prices.  In this low-yield environment, many investors rely too heavily on cash flows and to pursue this are venturing further into riskier areas than they’d normally consider.
