Meta has been testing a new integration in Threads called ‘topic tags’ for the past few weeks, and is now rolling it out to all users. Topic tags could be compared to hashtags, but according to Instagram chief Adam Mosseri, their purpose is to drive conversations in the app around specific topics.
Unlike how regular hashtags are used, users will be allowed to add only one tag per post. Moreover, for a tag to be functional, it needs to be composed manually in each post, therefore a post with a tag can not be copied and pasted for it to drive conversations. Another element that makes topic tags different from hashtags is that they can be created consisting of multiple words with spaces, without adding the ‘#’ symbol.
