What is a hashtag?
It’s a word or words led by the pound symbol (without space).
What is a hashtag for?
In tech-speak, it’s a metadata tag. In English, that indicates that it is a way to social conversations. On social media, the hashtag groups different social conversations to make them easier to find (and sorted by topic).
Do hashtags cross over on different platforms?
No, they do not. This means that hashtags are appropriate to whatever platform you are on. So even if the #Bachelorfinale is trending on both Facebook and Twitter, you’d have to search separately on each platform to follow the conversations.
Another favorite part of Twitter are hashtags, hashtags allow you to filter tweets by category/subject. This helps people stay in a social conversation without following all of those that are in the specific conversation or having them become followers.
