Yep. The thing is that just about everything is notable at a local enough level--whether local in the sense of geography or some other community. People who tend towards the deletionist side of the debate tend to try and get around this by falling back on verifiability--but that just, ironically, ends up favoring the sort of things that get printed on dead trees somewhere however obscure. As a result, it's much easier to make a case under Wikipedia rules that some selectman in a small town who is periodically mentioned in the local newspaper is notable than someone who wrote a widely-used piece of software but hasn't been the subject of news stories. (And, of course, there's no consistent practice either. I have to assume that lots of entries about obscure toys, games, and TV shows are largely original research.)
