Dividend Income: Dividend income is wonderful because it is completely passive and is taxed at only 15% if you are in the 25%, 28%, 33%, and 35% income tax bracket. If you are in the 39.6% income tax bracket you will pay a 20% tax on your dividends. My dividend income portfolio mainly consist of dividend equity and bond ETFs such as DVY, VYM, MUB, TLT, and IEF. Total stock and bond income is a little over $100,000 a year due to a heavy accumulation of stocks and municipal bonds after selling my house.

I've got a $185,000 CD generating 3% interest coming due. Although the return is low, it's guaranteed. The CD gave me the confidence to invest more aggressively in risk over the years. My online interest income has come down since I aggressively deployed some capital at the beginning of the year and again during the February market correction. You'll see these figures in my quarterly investment-income update.

The sheer traffic that the android and iOS appstores host every day means that if you are able to make an app that is useful, there is probably a market out there for it. If you are able to make a hit, then the sky is the limit. Flappy bird is a great example of the success that one person can have in their spare time. The creator is generating $50,000 per day from ad revenue on his free game. 
Viral marketing can be less expensive than traditional marketing campaigns, yet grow faster — especially with the help of social networks as a "force multiplier." Since it can receive so much traffic in a short time, it can also lead to mainstream media attention. Social media can also cause viral marketing efforts to misfire, as messages are altered, misconstrued, considered spam or called out for missing the mark. Viral marketing success can also be hard to measure.
Renting out a space room on AirBNB is really easy and their site handles the advertising, payment and feedback system. The process of having your site advertised is quite passive, but having someone in your house has similar risks to real estate investing, that makes it quite hands on. It is worth considering if you are rattling around in a large house, or have a granny-flat that is vacant.

Venture debt ($12,240 a year): The first venture-debt fund has returned almost all my initial capital, so I decided to invest $200,000 in the second fund. I took a risk investing $150,000 in my friend's first fund, so I'm hoping there's less risk in the second fund, given he has four more years of experience on top of his 12-plus years of experience running a venture-debt portfolio for another company.

Agreed but I might consider a blended portfolio of large and small cap stocks using low cost mutual funds (I found a fidelity large cap fund FUSVX with a net expense of .035% that has also delivered 17%+ YTD gains, some are dividend some are growth stock in the fund) UNLESS you’re close to retirement. This way you get the growth upside on small cap paired with the stablilty of some large cap stocks while maintaining balanced ricks.
Passive income differs from earned income and portfolio income in a variety of ways. Passive income is generally defined as a stream of income earned with little effort, and it is referred to as progressive passive income when there is little effort needed from the individual receiving the passive income in order to grow the stream of income. Examples of passive income include rental income and any business activities in which the earner does not materially participate during the year.

When money is lent to a partnership or S-corporation acting as a pass-through entity (essentially a business that is designed to reduce the effects of double taxation) by that entity’s owner, the interest income on that loan to the portfolio income can qualify as passive income. As the IRS language reads: "Certain self-charged interest income or deductions may be treated as passive activity gross income or passive activity deductions if the loan proceeds are used in a passive activity."

Wow! What an awesome list! My favorite is the stock photography because I love photography. I have had some success there, particularly with one photo I make some decent income from. I think the key with stock photography is finding a shot that is high demand. Then, find a new unique way to frame that shot. This is the reason my St. Louis Arch photo is a top 10 on both ShutterStock and iStockPhoto. Thanks for the awesome ideas above!

Haha, that is too funny. I wanted to make an app back in the day called “MyShares” (You can probably tell how I cam up with the name at the time). The idea was that I would loan out books and DVD’s and then would never get them back. Then I thought, how cool would it be if I could rent those items out and that would motivate people to bring them back. Obviously, books and DVD’s are cheap, so this isn’t the money maker. The idea that would probably make the most money would be things like tools, ATVs, etc.

It shouldn’t come as a surprise, but people who regularly monitor their finances end up wealthier than those who don’t. When you were a kid, keeping track of all of your money in a porcelain piggy bank was pretty easy. As we get older, though, our money becomes spread out across things like car payments, mortgages, retirement funds, taxes, and other investments and debts. All of these things make keeping track of our money a lot more complicated.
Do you want to reach new customers by promoting your online store’s best products? One of the hottest ways to reach more of your target audience is through viral marketing. Of course, it’s not quite as simple as adding cute animals to your marketing message, hoping that a kitten sitting on top of camping gear is enough to get your website link spread to the masses. But we’ll breakdown what steps you can take to help you inch closer to success. In this post, we’re going to look at how businesses can skyrocket sales through viral marketing.
Bob Gerstley was among the first to write about algorithms designed to identify people with high "social networking potential."[17] Gerstley employed SNP algorithms in quantitative marketing research. In 2004, the concept of the alpha user was coined to indicate that it had now become possible to identify the focal members of any viral campaign, the "hubs" who were most influential. Alpha users could be targeted for advertising purposes most accurately in mobile phone networks, due to their personal nature.[citation needed]
