For better or worse (ok, probably worse), the hashtag, @reply, and retweet have become inextricable from modern language, and it's hard to imagine a time when saying "hashtag blessed" would have seemed insane. But all things must originate from somewhere, and Quartz has managed to track down the founding fathers of all three.
Perhaps the most ubiquitous, the @reply, was actually just appropriating a shortcut that was already being widely used. Until that fateful day of November 2, Quartz explains that the "@" symbol was generally only used as shorthand for "at," and even then only to describe location. But then Robert Anderson (who now works at Square) changed everything.
Sure, there's technically a space between the two, contrary to current @reply protocol, but without him, it might never have existed in the first place. Hashtags, however, came about a bit more deliberately.
Quartz notes, "Not many people were impressed. Some thought hashtags were ugly and unnecessary. Twitter executives deemed the idea 'too nerdy,' according to Messina." But as we know all too well, that didn't last long.
Then comes the real trailblazer—Eric Rice and his RT invention.
When retweets finally started catching on, Twitter incorporated Rice's brainchild in November of 2009 by allowing users to automatically retweet others' tweets.
