Of course, you want your Tweets to post to as many news feeds as humanly possible. To do this, you have to get people following you. How’s that done? The most effective way I’ve found is to follow other people; most people will automatically follow your Tweets back.
Yet there are many people who do not participate in this courteous exchange, and they start adding up. If you are following 500 people, and only 100 of them are following you back, your credibility for good tweets decreases. (This will be necessary for a little while, though.) So the best thing to do is to find out who is not following your tweets, and get rid of them. But Twitter doesn’t make this easy. Luckily, there are outside applications to help.
The most popular site for this is Friend or Follow, and it’s popularity has lately caused the same kinds of bandwidth problems Twitter experiences in periods of high traffic. I prefer Twitter Karma, because, like Friend or Follow, it sorts users into followers/nonfollowers, but it goes a step further and makes unfollowing those people very easy. The site’s only flaw is that it can take a long time to load the program, and sometimes it must be reloaded several times before it’s up and running. But trust me, it’s worth it!
