Am I missing something? They clearly aren't supported on here, so why do some people use them in their questions?
This is probably one of those cases where the answer is obvious and I should know it, but I'm anything but an expert when it comes to technical internet stuff (which is evident in me calling it "technical internet stuff"), so I expect to be embarrssed shortly.
... in case it does indeed make no sense that some people use hashtags on here, please take a second to pat me on the back.
I've seen people use them in a lot of places that don't support them. I belong to a few online forums, and I see people use them in their posts. I don't get why when the forum doesn't support it. Maybe it's just out of habit from Facebook and Twitter? Maybe they just assume it will work anyway. I use an app called Whisper, and it doesn't support Hashtags but people use them all the time anyway. I read fanfiction on fanfiction. net and I once saw someone use them in their posts.
The only hashtag I've seen so far here were the ones I posted on a question that was something like "would you date a tall girl" where the girl was 5'8" and I said that ```I'm 5'7" so you wouldn't date me :( #tears #heartbroken``` and that was merely to illustrate the silliness of the post and not to take it completely seriously. Technically it's an expression of my terrible sense of cheeky humor.
Because hashtags can be funny. For example I don't have ig or Twitter but I'll still use hashtags irl. Say I'm driving and some idiot is acting like a turd in front of me. I'll probably rage and say something along the lines of "how can you be so fucking dumb, get off the road", then I'll pass him and see that he's Asian (don't even bother calling me racist, everyone's racist when driving). I'd say "hashtag Asian drivers".
I kind of think of them as "asides" ... like when a character in a play says something to the audience that isn't meant for the rest of the characters to hear. asides are meant to describe something further, be funny, etc and I think hashtags do that (especially when its a phrase)
of course hashtags were originally meant to "tag" posts and to be used in a utilitarian way but like most things there is the original purpose of something and then there is a social/cultural purpose. So I don't think people always use hashtags to "tag" a post and they use it to express some thought or feeling.
