Quartz: Elon Musk’s Twitter has even lost the man who popularized #hashtags

Quartz: Elon Musk’s Twitter has even lost the man who popularized #hashtags. “Arguably, Chris Messina created a monster. Back in 2007, Messina, a technology developer who was one of the first 2,000 users of Twitter, suggested using the hashtag symbol to group tweets dealing with the same theme or event. This way, these tweets could be easily found by Twitter users interested in that topic. But, like other monsters, the hashtag didn’t behave exactly as Messina intended.”
