Twitter has changed. It's no longer the domain of nerds and conferences but now serves the mainstream, not to mention pop stars with tens of millions of followers. Twitter's official app has changed with it, altering the way everything from the timeline to direct messages work and are surfaced. It's not what it once was, and its certainly not for everyone. While Twitter is no longer supportive of third party apps, and is actively trying to strangle them out of existence, many really good Twitter app alternatives still call the App Store home. And that's a very good thing, because many people use Twitter very differently. For some, it's just a way to follow celebrities or keep up with news. For others, its a virtual water cooler to chat around during work breaks. For yet others, it's a network to expand their social connections and market their wares. Different apps suit different use-cases. But which one is best, and for whom? Here are some of my favorites!
