Sometimes we are bugged by some commonplace behavior, belief, or attitude, but bringing it up will come off as obnoxious and elitist. We all have those. I will tell you two of mine, in hope I am not unknowingly a snide weirdo.
1 - And/Or is redundant: Just use OR
At some point it was funny in context (like "the OP is stupid and/or crazy). I can hardly find a context that is not similar to this (arguably) ableist template.
In formal logic there is no use case for saying 'and' OR 'or', because simply OR entails AND.
If there was a valid case it should represent the logical structure of 'AND' OR 'XOR', but it is obvious that this is OR.
So, whenever we are tempted to say "and/or" it is kinda definitive that just OR should suffice.
2 - A 'steep' learning curve means the skill is quickly mastered : Just use 'learning curve'
Apparently stemming from an embodied metaphor between the steepness of a hill and the difficulty of climbing it, this misnomer is annoyingly common.
I have yet to find a single source that does not yield to this erroneous, ubiquitous misconception.
Same goes for the fancier alternative 'sharp' learning curve.
In fact, in a diagram where the vertical axis is the skill mastery and the horizontal is time, a steep curve would mean that the task is quick or easy to master, since it reaches the higher level quickly, hence the steepness.
Since the literal alternative ('Rust has a smooth learning curve') will be counter-intuitive and confusing, and I bet nobody will adopt it, I suggest the following solution.
Almost every time you feel the need to reach for this phrase, YSK that probably just using 'learning curve' should suffice. For example 'This language has a learning curve'. It gets the message across, without making others question your position in the graph interpretation learning curve.
What are your mundane grievances?
This could sound like a dig on op but it's not, it's a different bugbear from elsewhere:
Thinking Linguistic Pedantry makes you a cool guy.
It doesn't.
Anyone who points out minor spelling mistakes as some manner of gotcha should be made fun of aggressively.
This guy (the guy who points out pedantic things), always thinks it shows how smart they are. Instead it shows how much of an ass they are.
Luckily here on the internet we all are to a degree so it doesn't matter. Goddamn those people at parties though, ffs yes I know the difference. I don't care. I'm at a party, it's douchey to bring grammar mistakes up at a party.
Oh they're insufferable on the internet too. It's worse at parties because it screams "bad room reading abilities" and "terrible social skills", but if I were to focus on that end, as autistic as I am, I would be doing a pot-kettle.
On the internet they bring down the level of the conversation, turn any discussion into semantic wankery, and generally make any thread they show up for unpleasant.
Except for making fun of people who write 'should of/could of'. I want to strangle someone every time I see that.
