Re: "My average day is spent behind a laptop reading Hacker News, Lifehacker, The Next Web, Smashing Magazine and whatever I happen to discover online."
how about you stop doing that for a while and crank your own side project. then you'll have smth to show, learn new stuff and connect with people.
desperation will probably not land you a job, but creating opportunities for yourself and showing how you can be useful to others may.
I've thought of that, but good ideas are hard to come by and a bad idea is never worth the execution. However yes, I need to be more active. This article is the first step.
The idea for your project is not important and neither is it's business potential. If it were, you would be hired for the position of CEO or head of marketing or whatever. Just do something, Anything that will show a potential recruiter your value.
