Hashtags? So what is that?

#Paderborn? So what is that? A hashtag!
Hashtags are currently on everyone's lips again are used in social media. Facebook recently introduced it, Twitter practically invented it, Instagram, Pinterest and LinkedIn provide the functionality, and Google+ too. But: what are hashtags and what are they there for? A short explanation:
In terms of structure, hashtags are words that are provided with a "#" - e.g. #Paderborn, #Bielefeld, #East Westphalia and therefore quite easy to set. Facebook, Twitter & Co. convert these hashtags and make them clickable (it becomes a link). If a user now clicks on this link, the respective service lists contributions (also from others) who have also used this hashtag. Basically, the message is grouped thematically by the sender and the articles are easier to search for the readers. You can also use hashtags as keyword or Label understand that are given to a contribution.

On Twitter, hashtags are mainly used for current topics, events or during discussions. This can be observed very well if you search for a keyword on Twitter (also works without registration), e.g. #summer, #Tatort or #UCfinal. On Instagram, the topic is more in the foreground, not the current reference - so hashtags are primarily assigned according to topic. The "grouping"
It is not yet possible to say exactly how Facebook will behave - but it should certainly be possible to mix the two use cases. Conversations on current topics are supplemented with hashtags as well as discussions or contributions on special topics.
So: watch out for hashtags. When used sensibly, they can make reading topic-related articles much easier.
