If you are using this survey to analyze your market potential I think you should be careful with your wording.<p>First, I would avoid asking <i>Would you consider using…</i> because it's not really relevant to you. Any good business person would consider using whatever you're building. I think it's better to ask: <i>Before starting this survey, had you ever considered x</i><p>Also, I think some of your terms (Real-time, analytics, public data stream) are a bit jargony which means people might not understand them and abandon the survey (thus skewing it to the opinions of people who understand) or worse, think they know what they mean when they don't mean the same thing as what you are talking about.<p><i>Edit</i>: Also wanted to add that you should probably add an 'I don't know' or 'I can't answer this question' option to prevent people from abandoning and to help determine which questions people don't understand.
<30 seconds is considered real-time? At the company I used to work for, all clients around the world had to get the same data in <1 second.<p>Does there exist a definition of "real-time" that can be used across industries?
