i wrote an iOS card game that makes me about 300 bucks a month. i do almost no maintenance on it anymore. it would probably do a whole lot better if it had any kind of marketing behind it, but it's not really in my nature.
I've read quite some remarks like that here and in other places, and I've said it about some pages of mine too.
Maybe it would be a good idea to build a marketplace where developers and marketing people can get together, and share the additional profit that the additional marketing generates.
If anybody wants to take up that idea, I'd be happy to be your first customer. Currently I'm just working on other projects (see another reply from me in this thread, for example), so I won't do it myself any time soon.
Sounds like something someone could pick up as a side-project and maybe even earn some passive income. :)
The gist of the article was that when he moved from writing new games, to marketing his existing ones (and other people's), he actually saw his income increase.
