If you are referring to the monthly jobs threads i was wondering the same thing, i would have expected more people searching for mobile developer (especially freelancers), but i guess mobile apps are not yet the new "website".
Over the past 6 months I've had multiple clients drop their mobile requirement to focus on web. I think it has mainly to do with scope creep and cost.
All those extra features that you can cram on a web page need that much more effort on mobile. People, for some reason, seem to be understanding that mobile costs a LOT of money, so they wait until later. But they expect to be able to build the web side really cheap, so they stick with that and argue price.
