The app TikTok was previously known as Musically and then I believe it was bought out and the name changed. TikTok is an app where users can create or view short videos. Originally users would lip sync or dance to songs but the app has recently taken many new directions. TikTok has quickly become an app where people can share information about a variety of topics. In which case, TikTok can be used professionally by brands, politicians, educators and experts.

With a quick search in hashtags you can find many educators using the app to share resources and connect with like minded individuals. You can connect with these educators to build your PLN by searching #teachertiktok or similar hashtags.
