Twitter, you can never follow enough people. The company has offered numerous ways to expand your lists, but this one will probably prove most effective. The Suggestions For You tab, rolling out now for most users (you might already have it -- check the "Find People" section), shows you users that might be relevant to your interests and / or are an extra degree off of our social circle. Worth a look, at least; if nothing else, you might find an account or two you thought you already followed (apologies to @engadgetmobile). And while you're meddling with your follow list, consider checking out our "Who Should I Follow" series for some more suggestions. Hey, editors need love, too.
