Pinterest is a photo sharing social networking site. Users can upload or share photos or web pages and organize them based on topics of interest.

As of 2016, 70 percent of Pinterest users were female, making it one of the most gender-specific social media networks.

The most popular topics on Pinterest are:

  • Food and drink
  • Crafts
  • Fashion
  • Home decor
  • Fitness and nutrition

The social media currency on Pinterest is a “pin” — users can pin articles, photos, or memes, which will include a link back to the source.
