I don’t mean to sound rude or nitpicky, but if I post a starter that’s five or six+ paragraphs long, and you respond with a single paragraph, chances are I won’t respond to you.
Not all the time, because it’s understandable- I tend to write humongous starters, but… I also put a lot of time and energy into making them and I’d like to be able to see that you’ve put a little effort into it as well.
This isn’t rude at all. You’ve an opinion, you phrased it very nicely.
That said, I have to disagree. When writing from the perspective of one character (usually) only, one often encounters circumstances where /literally/ all that character is doing is smiling and nodding, saying one thing, asking one question. Something short, sweet, simple.
I’m not spending paragraphs spinning that out; that’s a waste of everyone’s time. Mine as a writer especially. Starters in particular: those often are multiparagraph, due to the need to set the scene, mood, and theme. And I am /expected/ to respond with multiple paragraphs in return? That’s hard.
Me personally, I play in rps as third person limited, and I choose not to share what my character is thinking. I cultivate a somewhat laconic writing style, in part to make up for when my character gets verbal diarrhea and in part to stop myself godmoding. This means that there will often be times when all I can do is reply with a single line.
I do need to specifically address that last clause you have there. To assume that a short paragraph indicates the amount of time and energy put into it is short is to utterly ignore every possible thing about the other writer. Many writers agonise over every single word they put down, changing multiple times to make sure they evoke exactly the right thing. (Seriously, ask Elizabeth Bear. It’s almost funny, ‘watching’ her write.) It might have taken that person an hour to get that one paragraph exactly right.
In short, while your opinion is obviously valid, I disagree with it because I think you aren’t taking the other writer’s skill, style, or preferences into account when you react that way.
