TikTok is an app that allows you to create and share short videos. The videos are vertical, not square or horizontal size, like in Instagram or Snapchat stories, but navigation through the videos is scrolling up and down, like a feed, not touching or sliding from side to side.
Video creators have at their disposal all kinds of tools: filters, stickers or skins, voice-over; and above all, the possibility of integrating sounds to enhance the video. Users are also encouraged to interact with other users, via “reply” videos or “duets”; users can duplicate videos and add them.
Hashtags play a surprisingly important role on TikTok, because they let you mark up information and conversation topics. Unlike other social networks, such as Twitter, where the hastaghs allow positioning in information or last hours, the main function of hashtags in Tiktok is to “tag” specific content so that users can search and find them more easily. Hashtags actually exist as a real and functional organizing principle: not for news, or even to name trends or challenges, which are “challenges” or jokes, or repeated formats that perpetuate themselves.
