I would use a good natural language understanding api to do basic research, ideally monitoring many different feeds for topics of interest. It could also be a good way to monitor trends or competitors. I can't think of many uses cases for natural language as an interface to a traditional website. If there's something that's more convenient to access with text/speech, the user can just use set commands. On the topic of building a personal assistant app, from what I've seen the real value lies in the act of interactive scheduling. You can't say "schedule a meeting with george" without checking with george's schedule to make sure he's available, and potentially re-scheduling the event at a time of mutual availability. Of course this goes far beyond the scope of understanding language, but I think this is a big part of what will differentiate a good personal assistant app from Siri. EDIT: Someone on the thread brought up customer service, which is also a great opportunity. Interacting with a company's service representatives is a huge time sink for people everywhere, especially on the phone. Anything that lets people spend less time on hold is a huge win for mankind.
