I wouldn't consider a full time job at the moment. I'm not sure how people manage to hold down a full time job and build a startup on the side. I can imagine doing it while working a job which wasn't mentally demanding. But people working as full time programmers, I can only guess that they don't give 100% at work, or perhaps they have more energy than I do!
I've considered taking on the occasional short contract. But I'm not actively looking, I've got enough to keep me occupied with Readlang right now. (Plus, I've got a 1.5 month old baby, and they tend to reduce your free time!)
