Craig Newmark, the 66-year-old founder of Craigslist, has many contradictions, and his dedication to journalism is just one. He's credited by some with single-handedly taking down the newspaper classifieds industry and strangling local papers of revenue. In Feb, he gave $15 million to projects that support journalism at a time of deep political divide over where and how we get our information, and how trustworthy those sources may be. "So far, I've given over $90 million for this combined effort of trustworthy journalism, cybersecurity, countering information warfare," Newmark says. 

If there's ever a situation where you need to text a 911 operator instead of dialing the number directly, listen up now. The country's four big carriers: AT&T, Sprint, T-Mobile, and Verizon, will officially route texts addressed to 911 to your local police.

This is a good thing -- with more than 6 billion texts sent every day since 2012, being able to reach the police by typing rather than talking is a logical next step that could make a huge impact for people seeking help. But that doesn't mean you can -- or even should -- start texting your emergency instead of calling.

The first -- and most important -- point to understand is that although these four carriers have now enabled Text-to-911 on their end, they have no say over whether your local police station implements it or not. Each emergency call center, or PSAP (public safety answering point), as it's known in the public-safety sphere, has to decide how and when to allow Text-to-911.

Some already have, but others may take longer as they tackle a large set of issues that may include their size and financial resources. Not only do these PSAPs have to buy or license the right tools to carry on conversations over text, they must also establish protocols for communicating with texters, and then train their dispatchers. All of this can take time, especially in the face of a few thorns.
