That Twitter Pound Sign, Er, Hashtag

Anyone who has had a conversation about Twitter may have seen or heard illustrations like this:


What does that # mean?  Well the #, or pound sign, symbol in the Twitter world is known as a hashtag.  Putting this hashtag in front of a consecutive string of letters allows you to use that word or phrase as a category in a Twitter search.  So you can do a search for “#in” on Twitter and every person who has tweeted and referenced “#in” in their tweet would show up on the search results.

You can also save that search within Twitter so that if it is a topic you want to follow, you can reach it easier.
