As far as i know, a successful startup is supposed to make you rich or well off, but what about a web app that brings enough profit to replace your day job? That's an interesting perception. I have a web-based startup and I'm located in the Midwest. There is a huge entreprenuerial scene here, but web-based startups are as rare here as elevation changes. Of all the entrepreneurs I know here, the vast majority of them make just enough to get by with a little stability, and you'd be hard-pressed to find someone who doesn't consider that a success. I think a web-app making $1k-$2k a month with relative stability is a great thing to have, a good source of income, and even potentially a successful business, though by popular definition (as you pointed out), it probably isn't a "startup".
