For some, Ms. Jones’s account is how they watch the Olympics. John Moss, a business technology specialist in Atlanta, said he began following Ms. Jones on Twitter six months ago. When he does not have time to watch the Olympics, he checks in with her. “I experience the Olympics through her,” he said.

On Sunday, she tweeted about the fit of an skater’s suspenders. Mr. Moss had issues with her fashion take. (“Suspenders rock,” he commented.) “I thought, What is wrong with suspenders?” he said. “I wear suspenders.” He agreed, though, about her assessment of a snowboarder whose pants were bunched around his knees. “That didn’t seem right,” he said.

Ms. Jones is headed to Pyeongchang, South Korea, in a few days for NBC. There she will be a contributor, according to the network, and attend Olympic events, meet and interview athletes, and continue to tweet. Her followers wouldn’t want it any other way.
