why developers do it

Great post last month by Marco Arment (creator of my favorite app, Instapaper) on why developers don’t rush to new platforms.

We’re making iPhone software primarily for three reasons:
Dogfooding: We use iPhones ourselves.
Installed base: A ton of other people already have iPhones.
Profitability: There’s potentially a lot of money in iPhone apps.

I agree 100% with everything he says in the post, but can we use another phrase besides dogfooding?
