Our Nexus 7-a-day contest didn't end prematurely, it just got pushed back a day. You may have noticed some technical issues here at the site. We're doing some work with the servers and a few folks haven't been able to get to Android Central. We didn't think it was fair to have a contest for something as awesome as a Nexus 7 when folks couldn't get in to enter. Growing pains -- they happen when a website gets bigger then anyone imagined as fast as we have. It's all fixed up and should be sorting itself out as we speak. Erm, type.
The contest will pick back up tomorrow (bar any new and unforeseen circumstances), finish on Saturday, and we'll announce all the winners on Sunday. Keep an eye out for it.
