I know we've all seen a hashtag and we probably know someone who uses them to label every.single.thing they do. #perfectlife #livinglife #dranksomecoffee #atesomegrapes #pooped #goingtobed. But what the heck does a hashtag really do? Well, preceding a keyword with a hash character, or pound sign, (#) will identify messages on that keyword. So think of it like an archive of similar posts or pictures.
