A hash tag is simply a way for people to search for tweets that have a common topic. For example, if you search on #PUPPY (or #Puppy or #puppy, because it’s not case-sensitive), you’ll get a list of tweets related to the puppies. What you won’t get are tweets that say “I lost my puppy yesterday” because “puppy” isn’t preceded by the hash tag.
If you want to create a community of people with a common interest you can simply create a tweet with the hash tag in it. For example: Fellow puppy lovers. Let’s share tips and tricks by adding #puppy to our tweets.
Before you create the hash tag you will want to make sure it does not already exist. To do this do a regular Twitter search for puppy.
The possibilities are endless on Twitter if you use your creative thinking and stay up-to-date on the latest trends!
