Ask HN: How transferable are web dev skills?

I know some HTML, CSS, JavaScript (via jQuery mostly), MySQL, PHP, and basic web server admin (LAMPP stack set up and operation).

I work on hobby projects for myself.

I'm wondering where these skills can be transferred outside of the web development world.

I tried a little iOS dev once, just a very basic app, but I felt disconcerted by the hardcore object orientation and the naming conventions.
