People who saw it, who needed it, got it. Sorry, no some of the people who needed it got it. You have to be a person who is able to look at a general-purpose tool and be able to think, "How would I use that to solve my problem?" Most people are not that way. They look for a tool that is being used already for something close to their problem and then understand what it is. Many people who saw the spreadsheet with an example, if the example wasn't in their field, they couldn't make the leap. Because they're not programmers in their mind.
