Social media—engaging, personal, and best of all in this economy, inexpensive—has become the business tactic of choice for smart companies who want to connect with new and longtime customers.

Want proof? Just look at this list. When BUILDER joined Twitter in October, only a handful of builders were on the free online service, which allows users to send short (140 characters, max) updates to a network of “followers” about their activities. Our original list of “Tweeple” included just 10 builders and 16 other housing-related Twitters, from manufacturers to bloggers.

As you can see from the directory below, that list has expanded substantially. For now, we’ve broken the list down into magazines published by Hanley Wood (BUILDER’s parent company), Hanley Wood editors, state and local HBAs, builders, and other housing-related Twitter users who don’t fall into the previous categories mentioned.

To check out a specific person or company’s Tweets, go to www.twitter.com, add a slash ("/"), and then the person's username. For example, here is BUILDER Online's Twitter feed. If you want to hear more from them, log into your Twitter account, visit their feed, click to “follow,” and their updates will appear in your Twitter timeline.

If you don’t have a Twitter account, you’ll need to establish one and “follow” other Twitter users to establish your own personal newsfeed. If you are new to Twitter, it is sometimes easier to learn how it works by following people with whom you share an interest, such as wine, parenting, or cycling. Just do a keyword search under “find people” and you’ll discover countless people to “follow.” You may also want to see if news organizations in your city are on Twitter; the New York Times, Washington Post, Wall Street Journal, CNN, and others post headlines and links to major stories during the day.
