It doesn't matter what you're writing, using plain language doesn't mean you're dumbing it down. It makes it easier to read and understand what you're trying to say. You can take corporate jargon as the opposite of this. It can be vague, different people will have different definitions of certain words.
I think it's heartwarming gibberish but there is also, I think, a legitimate role in the discourse for heartwarming gibberish. Sometimes you have to explain what being trans is to a person who believes that dogs go to heaven and, in most circumstances, saying "I'm a female soul in a male body" gets the point across.
As a disabled, trans, vegan, anarchist my life and beliefs are far more complicated than I could express in a comment section. So I tend not to lead with any of those labels and instead focus on quippy one liners about personal liberty from goverment or religious institutions.
No random person wants to read my nuanced memoirs, but they will read and remember pithy snark. I'm an anarchist that sounds like a libertarian fool, but it's the language that more people in mixed company relate to.
Not often. Certainly not when I'm shouting into the void.
When I'm answering a question or responding to a statement, I'll generally match the level of the existing discussion. I still try to say what I mean, but I'll try to avoid concepts with a lot of missing prerequisites. Target audience matters too, if you ask me how orbital rendezvous works, you'll get a different answer depending on where you ask the question. For example, I'd probably skip explaining how orbits themselves work if you asked in a community dedicated to kerbal space program or children of a dead earth, focusing instead on what the person asking is probably trying to do. Similarly, a comment in a community dedicated to real life space exploration is getting a more detailed answer than the same question in a community for the general public. Basically different assumptions about what the person already knows, and what the person wants to find out.
I think everybody should "dumb themselves down" on social media. Since you can only assume other people's background on a given topic and their grasp of (for example) English, you should write in a way that's understandable to as many people as possible while still getting your point across. That's just how good communication works.
I wasn't just talking about using a cleaner style of speaking either. Choosing topics and the depth of these topics is part of communication as well. Those should be picked according to prior cues (the community you're in, previous exchanged comments etc.)
if anything i smarten up. text allows me to organize my thoughts and analyze my word choices. i can say much more and provide more detail over text. when i talk i feel stupid lol.
I almost never do. It's actually a bit weird, I tend to ramble more in writing than I ever would while speaking and usually end up with mini-essays even for relatively straightforward ideas.
This is two-pronged, partly because I enjoy writing and expressing myself through it more than I do speaking, but it's mostly because I'm obsessive about conveying nuances with as much precision as I can, especially in a medium as restrictive to conveyance as writing is (thinking about not having non-verbal and other purely contextual cues at my disposal).
It's not like I intentionally bring out the expensive words just to flaunt my vocabulary (I even have issues with being perceived as pretentious), it's just that some things simply require the extra precision when expressing their full complexity.
I think that there is a fine line between dumbing something down and sounding condescending. In time, I found that not treating people like morons is the best approach, i.e. accessible language and simple explanations must be used to aid in the speed and understanding of the information you are disseminating.
Because nobody wants to sit there and brainstorm something they don't understand, they'll just move on. But if you treat them like babies, people will just be annoyed and stop paying attention.
So its quite the nuanced subject, communication is an art-form.
We've all seen the "I'm very smart" people who come to social media, use random vocabulary vomit because they want to sound smart, and it happens here a lot. I agree with you, that's great if you can, and I won't say you "have to dumb yourself down", but often they do it to sound smart and want to feel superior because they think most people understand.
Actually a lot of people do understand them, they're just eye rolling at how pretentious they're being.
There's a balance. After all why use many word when some word do trick?
