Now the machines seem to have dispensed with the slowpoke humans. Just how big a role computers played in Tuesday's brief market swoon is uncertain. But, according to some experts, when human traders read a fake news tweet and hesitated to buy, the computers took over and went into sell mode. The result, they say, was a market completely on autopilot, at least for a few crucial seconds. What are the risks of such a market and should it be regulated? By Bernard Condon and Matthew Craft.

But this online method of soliciting money from investors may be more of a bust for many small business owners. People involved in venture funding say entrepreneurs may find that investors aren't interested if their companies don't have a good track record or the promise of a good return.

Nine years and hundreds of saved songs later, Braff hopes he's finally making his follow-up to "Garden State" â¿¿ if his fans can help. On Wednesday, in the wake of the enormously successful "Veronica Mars" Kickstarter campaign, the "Scrubs" star launched a crowd-funding campaign to make his next movie. For the next 30 days, he'll try to raise $2 million on Kickstarter for "Wish I Was Here," a film he co-wrote with his brother Adam. By Entertainment Writer Jake Coyle.
