Social media opens up both conversation and creativity for stock traders. But most importantly, it creates community around niche interest topics.
The way stocks are discussed among investors is different than it was even five years ago. In 2008, Howard Lindzon launched StockTwits, the online community of investors, with the idea that people wanted to share ideas about trading. Lindzon was a huge fan of Twitter, and so StockTwits was built off of that.
“A guy in Kansas can be the expert on grains, rather than the guy who trades grain stocks in New York,” says StockTwits CEO and Founder Howard Lindzon. “The Kansas guy can look out his window and tweet what he sees.” StockTwits, says Lindzon, has turned everyone into a potential market maker and expert.

Sarah Benson last encountered college mathematics 20 years ago in an undergraduate algebra class. Her sole experience teaching math came in the second grade, when the first graders needed help with their minuses.
And yet Ms. Benson, with a Ph.D. in art history and a master’s degree in comparative literature, stood at the chalkboard drawing parallelograms, constructing angles and otherwise dismembering Euclid’s Proposition 32 the way a biology professor might treat a water frog. Her students cared little about her inexperience. As for her employers, they did not mind, either: they had asked her to teach formal geometry expressly because it was a subject about which she knew very little.
It was just another day here at St. John’s College, whose distinctiveness goes far beyond its curriculum of great works: Aeschylus and Aristotle, Bacon and Bach. As much of academia fractures into ever more specific disciplines, this tiny college still expects — in fact, requires — its professors to teach almost every subject, leveraging ignorance as much as expertise.

Like every other taxpayer-funded public service, libraries have been hit hard by budget cuts during the economic slowdown of the past several years. Adding insult to injury, fewer people read, and those who do are increasingly likely to use e-readers instead of print books. Those forces have combined to send many libraries searching for new ways of doing business.
One of the most innovative new initiatives comes from the City Centre Library in Surrey, British Columbia, which is scheduled to open next month. Realizing that bound volumes are far from the only source of knowledge, librarians in Surrey will also lend out “living books”—in other words, people. Staff will maintain a list of local residents who have volunteered to share their knowledge of any topic, and other library patrons can make appointments for 30-45-minute conversations.

The US has lost or is on the verge of losing its ability to develop and manufacture a slew of high-tech products. Amazon’s Kindle 2 couldn’t be made in the US, even if Amazon wanted to:
- The flex circuit connectors are made in China because the US supplier base migrated to Asia.
- The electrophoretic display is made in Taiwan because the expertise developed from producting flat-panel LCDs migrated to Asia with semiconductor manufacturing.
- The highly polished injection-molded case is made in China because the US supplier base eroded as the manufacture of toys, consumer electronics and computers migrated to China.
- The wireless card is made in South Korea because that country became a center for making mobile phone components and handsets.
- The controller board is made in China because US companies long ago transferred manufacture of printed circuit boards to Asia.
- The Lithium polymer battery is made in China because battery development and manufacturing migrated to China along with the development and manufacture of consumer electronics and notebook computers.
