I enjoy the stack exchange network because it enables me to indulge my inquisitiveness. I'm currently focusing on learning General Relativity - as far as this is possible for someone learning in their free time! I have a degree (but not a PhD) in physics, so I am not completely lost - but my education was sadly lacking in GR. This is a pity, but sadly not uncommon.
In the 'real world' I work as a software developer :D
