Did you know?

Hashtags are an everyday part of Internet culture, thanks to social media. Originally designed for categorizing posts (i.e., tagging them) on Twitter, hashtags now commonly also supplement or comment on whatever text or image they accompany. The “hash” in hashtag is short for hash mark, a term for what we also call a pound sign or, if you want to apply the word-nerdiest designation, an octothorpe. Hash in this case is probably an alteration of hatch, a term for the lines artists sometimes use to add shading to a drawing. #WordNerdery
