#3: Build Your Twitter Network
Twitter is a network that lets you communicate in 140-character messages. You can answer questions, forward interesting articles, and find new opportunities on the 200 million member network. Of course, you need to build your Twitter network first.
The first place to start is on Twellow.com, which is the Twitter Yellow Pages. This lets you find people based on their bio. Use the directory to find people in your industry, and connect with them.
Next, use Twitter.com or TweetDeck.com to create lists of those people so you can more easily monitor their conversations and stay involved with them. Also use TweetDeck to do an ongoing search for industry keywords. When people use those words, check to see if they're asking a question, tweeting an article, or just making a comment. Then, answer, retweet, or respond to stay on their radar.
