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]

Income-generating assets are another of many passive-income opportunities. A classic example is making money in real estate via owning rental properties. It can seem perfect: You buy an apartment building or house, rent it out, and then sit back and collect checks every month from your tenants. The reality isn't always so rosy, though. For one thing, you'll need to maintain and repair the property, as well as paying taxes on it and insuring it. It may not always be occupied, either. You may have trouble finding tenants, or finding tenants who pay their rent reliably. Some tenants may damage the property, and others may be hard to get rid of. You'll be the one they call in the middle of the night if the roof is leaking, and you'll have to clean and perhaps freshen up the property between tenants. You can outsource much of this to a property management company, but it will take a cut of your income, often about 10%.
