LinkedIn
LinkedIn took a more serious approach to social networking.

#hashtag is born
The purpose of the hashtag was to make it easy for users to search for content and find specific updates that are relevant without the technological knowledge to navigate the site. So basically, the hashtag "was created organically by Twitter users as a way to categorize messages." Hashtags are now used on Twitter, Facebook and Instagram. https://en.wikipedia.org/wiki/Hashtag
