Ask YC: Just quit my day job to work on NewsCred fulltime. Looking for marketing inspiration.

I finally did it! Yesterday was my first full day of 100% entrepreneurship. Things were taking off and I'm excited to finally be able to give full attention to my real passion. Quite daunting, but exciting. So now that I'm full time, my few weeks will be spent on marketing and user acquision. Any pearls of wisdom or inspiration for interesting marketing campaigns?
