The A-Z Dictionary of Educational Twitter Hashtags – Edudemic   Leave a comment

“Whether you’re a new or seasoned Twitter user, you likely come across confusing hashtags that probably look like a bunch of nonsense.

First, What’s A Hashtag?

The # symbol, called a hashtag, is used to mark keyword or topic in a Tweet. Any Twitter user can categorize or follow topics with hashtags.Those hashtags (usually) mean something and are a great way to get a tweet to appear in search results or discussion monitoring.

For example, the popular #edchat hashtag is used by thousands of users every Tuesday. It makes it easy (sort of) for people to monitor what’s happening in the conversation rather than having to try and guess what topics you should search for. By having a conversation on Twitter using hashtags, you also make it easy for any other Twitter user to join in.

How To Hide Your Hashtag Chat From Followers

When having a Twitter #hashtag chat, if you want to avoid overwhelming your followers, start any tweet you want to “hide” with @HideChat or (one character shorter) @HideTag. (Do NOT follow @HideChat or @HideTag. They exist only to help you hide your Twitter chats.) NOTE: This also works when live-tweeting events or shows.

You don’t need to do this with all your chat tweets (though you could). But it’s a good idea to do it with most of them so as not to overwhelm folks. You could also use this for conversations with someone that you didn’t want others to notice in your timeline, although direct messages would work best for that.


That’s why it’s probably helpful for you to check out the following list of popular educational hashtags. They have been curated by Cybraryman as well as by the Creative Education blog, our personal usage list and
