How do # work?
Everytime someone is using a specific # to describe a caption, it will help the platform categorize it, so that the person who is interested in the same topic, will find it.
It works like an organizer.
This is where it is getting interesting, because there are thousands of # being used currently and new ones are created daily.
You can create your own # if you want.
Let say you create #Iwillteachyoueverythingabouthashtagstodaysoyouwillmasterit
Yes you can.... but you might be the only one using it... and that is not necessarily what you want .
(unless you are creating your brand #, but we will talk about that later).
