As a writer who loves to write in prose and paragraphs, I must say that writing in script for doesn't really get you anywhere but laziness...this might sound rude but I'm sorry because that's how I see it. I've been noticing quite a lot you know, a lot of new writers who post in the thread write in script form, basically because its easy and isn't that time consuming, well, that's fine cause the thread would get more fics by then, but that just promotes laziness. Since script forms are easy to read because they aren't that too detail and are short for read, it promotes the readers to get used to reading short texts, meaning, they won't even like to read anything long like those in prose and paragraphs, and that's the problem now since people this days don't often read that much anymore.
There's actually something good that comes out of writing lengthy ones because they expand your vocabulary use and challenge you, I actually learned a thing or two from doing this and it basically helps me in my essays, and also the fact that fics written in paragraphs are actually ones that are enjoyable to read because they give something to imagine with all the hints dropped by, I find myself captivated and awed by those writers who write in this format because you can clearly see their styles in writing.
I'm not trying to say that script forms are bad, but seriously, sometimes it doesn't make sense of its all just lines with little description, it doesn't really give that much background to the story if it stays like that too. Sure, script form is good, but its good for comedic purposes, but if an author is trying to aim for a story with an actual plot, I think they should give more background to the story since script form does not in anyway give out that much details but lines only, I've read most of them and not one fic in script for can easily move me to tears if they were trying to bat for the angst genre, but it works for comedy.
Also, using drabbles as an excuse, did you know there's actually a rule for drabbles? I haven't heard such a thing as a long drabble actually. A drabble consists of exactly 100 words. It's a rule, and the very reason why its limited to 100 words is to challenge the author on how to place their ideas while limiting it to 100 words and if you were to violate the 100 word rule, then that wouldn't be a drabble anymore. There's an actual historical background on this so I'm not making up anything about this.
Anyhow, I do think script formed fics should be separated from the prose and paragraphed ones. I'm not that much a fan of script unless its comedy, I'm more the type to read paragraphs, so this would really help for an easy browsing process.
And again, I am not saying scripts are bad, its just that you should moderate the use of it and also try to write in paragraphs. Its alright to write in scripts, but you should also try to switch sometimes instead of just staying in one place.
