Two years ago today, TED.com posted its first six TEDTalks. It was a radical notion to share these powerful talks and ideas with the world — but it looks like it was the right notion. This week, TEDTalks notched its 50 millionth view, and we moved to a daily publishing schedule to keep up with the demand for more great talks, performances and conversations.

Celebrate with us by suggesting your favorite TEDTalks over the past two years. Count down the Top 10 TEDTalks in a special Theme page, where you can discuss the talks and suggest your own hidden gems from the archive.
