A common reason given by those who have yet to try Twitter: “I have nothing to say.”

The truth is, you don’t have to post a message to get the most out of Twitter.

At its best, the social medium is a perpetual, personalized news service about topics of your choosing — health care reform, tech news or the latest episode of “Gossip Girl” — filtered and served to you by people who share your interests.

Even the most prolific users say Twitter has become more useful as a way to tap in to the discussions of the day than to broadcast their thoughts. And once you get pulled in, you might just find you have something to say after all.

Biz Stone, one of Twitter’s founders, suggests that naysayers simply log on to Twitter’s home page and search for a topic they are interested in, whether it’s their favorite sports team, the name of their company or a topic in the news.

Within a minute, they understand the appeal, he said.

Twitter users write 50 million messages a day. For the holdouts, here are a few ways to make Twitter work for you:

A Custom News Feed

By the time Bridget Baker, who works in public relations in Seattle, checks Google Reader while eating lunch at her desk, she has already read most of the articles in her feed because she saw them on Twitter.

In the year since she joined, she has written only 17 posts. “I tend to be a pretty private person, and I don’t feel I have anything that needs to be said,” she said. Yet she opens Twitter first thing each morning and follows friends, bloggers and thought leaders who post about politics, religion, fashion and food.

People with shared interests become your editor and Twitter becomes an alternative RSS feed. Find those people by searching Twitter directories, like WeFollow or Just Tweet It, and by following people whom others repeat or mention.

One-fifth of posts and 57 percent of repeat messages contain a link, proving that this is an increasingly popular way to spread news, said Dan Zarrella, a social media scientist who works at a software company called HubSpot. A quick scan reveals the news of the moment as the most important stories of the day bubble up and are reposted.

For instance, when Audi showed an ad for a green car during the Super Bowl, Chip Giller, the founder of Grist, an environmental news site, immediately noticed a debate about the car’s environmental merits on Twitter. Sure enough, it was a big story the next day.

Check Your Lists

Twitter is such a fast-moving stream that you may not want to follow everyone who posts about interests you share. That’s one reason Twitter invented Lists, which anyone can create. Someone could separate celebrity users, owners of food carts in New York or tech pundits, for example, so they get an unadulterated stream of news on only the topic they want at that moment.

If you don’t know who the best users are on a favorite topic, look for Lists on sites like Listorious or by checking profiles.

Janessa Goldbeck works in Washington for a rights organization, the Genocide Intervention Network. Each morning, she checks a few Twitter Lists of people who work in human rights. “I don’t want to follow all those people, but I can get a snapshot of the landscape each day by looking at the Lists,” she said. “It’s the quickest, most personalized news filter you could imagine.”

Attend a Conference, Virtually

Most conferences these days have a Twitter hashtag. At the exclusive Technology Entertainment Design conference last month in California, for example, attendees added #TED to the end of their posts.

By searching #TED on Twitter, users could get the latest updates (and skip the $6,000 attendance fee). People wrote quotes from the speakers, like this one: “‘If I only had only one wish for the next 50 years, it’d be to invent the thing that halves the cost of CO2’ — Bill Gates #TED.’’

Sometimes not being at the actual event is an advantage: “last talk on evolution #TED was obvious, boring and put audience to sleep.”

What’s Around You Right Now:

Twitter is working on ways to deliver news nearby, like alerts about an earthquake or the closing of a bridge, Stone said.

Twitter’s list of trending topics can now be searched by city. On Wednesday, “TAKS” was a trending topic in San Antonio because schools were giving the annual achievement test of that name, while “Dennis Seidenberg” was trending in Boston because the Boston Bruins had acquired the hockey player from Florida.

Some Twitter apps, like Tweetie and TwitterLocal, let you search posts in your area. Check the Web site Happn.in to see the most discussed topics locally.

People are also coming up with makeshift ways to do the same thing.During the recent snowstorm in Washington, users added #snowpocalypse to the end of their posts. By searching the term, Goldbeck said she read news about closings of government offices and Metro stops before she heard it elsewhere.

Ask Questions:

Once your Twitter writer’s block lifts, you can use the service to post questions when you don’t know whom to ask.

Ask where to eat dinner in a new city, for example, or how to extend your iPhone’s battery life, and you are sure to get answers.

Some people are even using Twitter for more urgent questions.

Bertalan Mesko, a medical student at the University of Debrecen in Hungary, wrote a post about a patient with mysterious symptoms: “Strange case today in internal medicine rotation. 16 years old boy with acute pancreatitis (for the 6th! time). Any ideas?”

Within hours, specialists worldwide had responded, suggesting gallstones, lupus or growths on the pancreas. One of the suggestions helped the doctors find a diagnosis.

“It would have been impossible to find that specialist through e-mail, because we had no idea who to contact,” Mesko said.
