What is a (#) Hashtag?

Thanks to the member-driven online information site Twitter, the lowly “pound” or “number” symbol “#” has been elevated to a new role. The hash mark, or pound symbol, (#) is now known by social media users as a “hashtag” or “hash tag”. Posts that have the same keywords prefixed with the # symbol are grouped together in user searches, bringing a level of order to the frenzied chaotic world of Twitter.

Twitter user Chris Messina (@chrismessina) first Tweeted with a hashtag symbol # in August 2007, as a way to define groups on the social media site. The use of the pound symbol to categorize messages and define conversations spread quickly throughout the Twitter community, and is now an integral part of this fast-paced live information network.

I can’t resist adding some Internet history along with the information about hashtags.

Hashtags can be used or organize information, create an archive or directory for a group of people. But, I think hashtags are just fun. Stick together a phrase (shortened for space) and add it as a sub-commentary to your post.

Don’t take hashtags too seriously.
