Hash Tags

Hash Tags

A Hashtag is a word or a phrase prefixed with the symbol #. It is a form of metadata tag. Short messages on microblogging and social networking services such as Twitter, Tout, identi.ca,Tumblr, Instagram, Flickr, Google+ or Facebook may be tagged by putting “#” before important words, either as they appear in a sentence, (eg. “New artists announced for #SXSW 2012 Music Festival!”) or appended to it.

Hashtags provide a means of grouping such messages, since one can search for the Hashtag and get the set of messages that contain it. When another user uses Hashtags to find a particular word, they will see all posts containing that Hashtagged word. It’s a really handy skill to learn, as social media becomes the primary way we communicate.

The social media universe is vast and can be a little confusing to navigate. Hashtags are one of the most important and efficient ways of organizing information on various platforms like Twitter, Facebook, Google+, etc.

Anyone can make a Hashtag at any time, simply by typing a phrase of the form “#topic” in a tweet. The form for doing this is exactly the same as for including an already existing Hashtag. Simply type a phrase of the form “#topic.” Do not put any spaces in the phrase that you want to turn into a Hashtag, because the Hashtag begins with the “#” and ends with the first space. When you click “Tweet”, your new tweet will appear in your list of tweets, and the Hashtag you created will appear in blue. Scroll over it and click on it to be redirected to the page for the Hashtag. If you have really created a brand new Hashtag, your tweet should be the only one on the page. Now, every time someone includes your Hashtag in a tweet, it will be added to the page.However, a lot of Hashtags have already been created and in main stream use.

I have linked the following examples to Twitter, but these examples are also used on a variety of other platforms listed above, think Facebook, Google+, etc.

  1. #Antibiotics – Antibiotics
  2. #CochraneEvidence – Cochrane Evidence
  3. #CritCareEP – Critical Care Emergency Physicians
  4. #DigitalHealth  – Digital Health
  5. #FF – Follow Friday –  It’s a Twitter trend created back in 2009 by Twitter users that has since become a customary Friday activity. An #FF is a shout out, a show of appreciation, a nice thing to do. Each Friday you recommend Twitter profiles that you appreciate and enjoy to all of your followers. The idea being that your #FF recommendation will encourage others to check out that profile, generating more followers for them. See? A nice thing to do. This is usually done in list form, with users tweeting a list of usernames along with #FF, so that people who trust their judgment can add a bunch of interesting accounts to their feeds.

  14. #TBT – (Throwback Thursday) This is another “holiday” Twitter and Instagram hashtag, which shows up every Thursday on both sites. The impetus behind this one is that it is an opportunity for people to share photos and info that is a “throwback” to an earlier time. For instance, on Instagram, posting a picture of yourself as a child or when you were in school, or on Twitter telling a short quip about something in your past. This is a fun way for people to learn a little bit more about each other, and to see the funny or interesting past that each of us have, but many of our followers and friends don’t know about.
