You are not. To be fair, I also have a few products that I've shipped but that didn't go anywhere -- of course, I didn't really expect them to as I didn't really do anything in the way of marketing or anything, but they're out there (or shuttered).

In my case, for the most part, I'll either come up with an idea or a challenge. In some cases, I'll work towards an idea and usually, I'll get further along with those because I start with the boring stuff like logins, user profile pages, etc.

With the challenges ("How would you build a web site that did <insert something novel here>?"), those are pretty much guaranteed to be DOA. I do the hard part, sometimes realizing my initial approach was stupid, starting over, and then doing it more elegantly, and then uhhhh, well, that's it. The chance of me writing all the boring crud for something like that to make it multi-user is infinitesimal.
