The program seems to have a small user base, and, judging from comments by users on the various fora (see below), a handful of them seem to have trouble figuring out how to use and what to do with it. I believe this is because one is actually required to think, sometimes rather hard, to make effective use of Tinderbox. I slipped right in to productive use of the program right away, but I think this is because I had been thinking about how I might use something like Tinderbox before I discovered that it existed. It is also rather difficult to evaluate the program, as the free demo version is severely limited, but if, like so many people, you have hundreds or thousands of scraps of information on your hard drive, and you have been looking for a way to keep them and their relationships to each other organized in a way that is more flexible and visually suggestive than a traditional database, you must give it a try. This is doubly true of you need to export part of your information morass as a website or something else, because Tinderbox is quite flexible in this regard.
