You can reach people on Twitter, but there's some question as to how much you can influence people. Periodically I see articles from people with hundreds of thousands of followers who admit to being unable to translate that into sales, or hits to their site, or votes, or whatever. Twitter is a great platform to keep your name in the public consciousness. So... indispensable if you're a Kardashian. Other than that, though, it's not clear. A lot of people are wasting a lot of time building up a subscriber account that ends up being meaningless. Facebook makes money because people give it a lot more information than they give twitter. Too much, IMO.
