Google trends is a great site to check out if your curious about trending topics. Whether you are curious about technology, fashion, stocks, celebrities, etc. It’s all there.

Also, if you enjoy Google Trends, you’ll want to check out Google Zeigeist too. It’s a collection of the top terms for the last year.
