Over the years, I've developed a number of steps to keep my twitter feed healthy (i.e. interesting).
- Every time I see a tweet that's not interesting or relevant, I will click on the twitterer's profile and check the last updates. If I don't see an interesting one, I'll unfollow. Obviously, there was a reason why I followed this person in the first place, but not any more —nothing personal.
- Whenever someone interacts with one of my tweets (star, RT, reply) or follows me, I'll check their profile. If they find my tweets interesting, there's a good chance I'll find theirs too. That's not always the case, but it's worth checking.
- Whenever I read an interesting blog post or article, I'll check the author's twitter feed and I'll usually follow them.
- Whenever a person I follow retweets, or replies to someone I don't follow, I'll check if this is someone I should follow.
