Chevrolet switches up its content by showing what its followers expect: cars, cars, and more cars. By hashtagging its tweets, the automaker can keep track of the conversation (although it uses it a little too much). Ultimately, it keeps things interesting by mixing up content and encouraging followers to get involved.

Similar to Chevrolet, Ford does the usual mix of photos, links, and hashtags, but places a greater emphasis on creating a personal feel.
