When did tic tac toe become a hashtag? #

@Fernie: Twittering this, twattering that...I tell ya...

@Meowsolini: I actually did just LOL at that

@Fernie: 😜

is that where hashtag started? It's quite irritating imo

I think so. It's was the first time I'd ever seen it used that way. And yes, it really is irritating

it's also the sign for numbers
