The only way is choose the right person to follow. You should determine which sounds you would like to listen to. More specific, more accuracy. For example I just focus on several fields: javascript, node.js, python, machine learning. So I find the users who often tweets these contents. But don't get a lot at a time. Just several ones. Because you need to observe them and measure their posts a week or more. During that period, if someone posts something you don't like. Let's unfollow him and find another candidates.
Twitter is great place. It's different from Facebook. You should not follow someone just because you like him or admire his reputation. Never! In Twitter, the only thing we really care about is content, not person.
