TopNewestBrilliant has really been like a boon to me. Until I started solving problems on Brilliant, I used to be weakest in Maths(during 11th). Gradually it has become my strongest subject and now I look forward to solving Maths. I would like to thank the Brilliant community for posting such nice questions. It has been a truly wonderful experience here.

Hi Azhaghu, good question! We had a beta version up and running for a few weeks in the summer of 2012, and then we took the site down for a while to work on making it much better. We consider October 28, 2012 to be our official launch date.
