A colleague asked me to help an undergrad student learn to use hashtags in Twitter. My first inclination was to suggest a bit of learning-by-doing-the-research-yourself, but before giving that answer I decided to do a quick search and see if an easy answer was readily available. To my surprise, it seemed that while it’s easy to find a lot of overly complex and/or kind of outdated information, some of the basic concepts were a bit buried.
So, I’ve decided to write a brief list of hashtag pointers and post it here.
– a hashtag is a word (or string of words with no spaces) beginning with the # symbol
– you can find lists of commonly used hashtags, but anyone can create a hashtag at any time so it’s a very dynamic and flexible tool.
– there are many ways to use twitter (twitter.com, tweetdeck, cellphone apps, etc.) and all have ways that you can search and sort via hashtags.
– If you use twitter.com from your browser, clicking on a hashtag in any tweet is an easy way to search for other tweets that use the same hashtag.
Here are some twitter screenshots with hashtag examples (and my explanation of a likely reason why the tweeter used them):
Tweeter Shannon Miller has used the #Educon hashtag to refer to an educational conference. Using hashtags to tweet about conferences is a great way for everyone, whether they’re attending or not, to keep up with what’s going on during keynotes and other conference events. Many conferences provide an agreed-upon hashtag so all tweeters can use the same one. It can be really interesting to follow a conference stream of tweets in this way.
Tweeter Joe Bower has used two hashtags in his tweet. #Edchat and #edtech are basically twitter ‘conversations’. You can participate in real time as these conversations usually have a set “meeting time” but you can also search the tags at a later point (but not too much later because after a few days tweets might not show up in your searches) to see what happened. For a previous blog posting of mine mentioning edchat, see https://elizabethtweets.wordpress.com/2010/04/13/edchat/
Airport codes (yyj is Victoria BC) are often used so that region-specific tweets are easy to find and in this case, the #yyj tag is much better than #Victoria because “Victoria” could be a person’s name, a place in Australia, etc. Also, the airport codes are nice and short so they don’t use up too many of those precious 140 characters.
This is my tweet, and I’m using two hashtags that have been created by other tweeters. Sir Ken Robinson set up the #askSKR as a way for him to track when people ask him questions. The #sirken tag came to my attention when Joe Bower set up his blogathon.
– Tweets can include as many hashtags as will fit in the 140 characters, but hashtags can be overused which makes the message difficult to read. There are no rules about this, but common sense will probably tell you if your tweet looks cluttered.
– Hashtags can be used as a way for you to find those “kindred spirits” you should be following. For instance, I have found people I’ve wanted to follow because they tweet about creativity and use the #sirken hashtag to reference Sir Ken Robinson.
