The market segment for paying customers is small, largely due to little value added. Even with their set of "enhanced search/stream" tools, companies will only benefit if users are commenting on their products. That goes to say, if companies are popular, they will hear that they are popular. Little known companies will not hear valuable opinions on their products. Furthermore, analytics will be skewed since the twitter community is a particular set of people.
Also, a large question would be: Who gets to choose between personal and commercial? If I have an personal account where I talk about work, is this a commercial account? The "web evangelists", marketing, and branding "gurus" - do these guys need commercial accounts? Does the size of the company matter? C-Corp or Sole Proprietorship?
While I do want to see Twitter succeed, I feel like they have other, more appropriate alternatives that could be feasible.
