I'm curious about this because Reddit seems like a great place for science fiction writers to critique and learn from each other.

I don't see that happening, and it's a bit puzzling.

There are two main subreddits for science fiction writing critiques, and both of them suck, for different reasons.

-- 1. /r/SciFiWriting

• Has a terminal case of "hostile, angry moderator syndrome". Just look at the sidebar.
• Draconian rules for submitting stories and offering critiques. If you need an entire wiki of several pages' length to "educate" people about how to post stories and talk to each other, you're doing it wrong.
• Restrictive formats for story submissions. Forcing writers to use Google Docs or PDFs sucks. Not everyone wants to create a Google account just for their stories, and there's nothing wrong with posting a story to a Wordpress (or other) blog.

-- 2. /r/DestructiveReaders

• Has a terminal case of "we created this subreddit to invite people to act like self-important, know-it-all trolls" syndrome. See also: the reason why it's called Destructive Readers.
• The entire subreddit is seething with frustrated wannabe grammarians writing bloated arbitrary rants about each others' stories in order to satisfy the "review a story before posting one for review" rule.
• The moderators also encourage users of the subreddit to harass each other and talk trash -- but not to talk trash about the stories themselves. How that's supposed to work is a mystery; all I know is that it's a massive and unnecessary waste of time to sort through reams of trash to find an intelligent review.

Another problem that the larger Internet has noticed, and Reddit tends to ignore, is the culture of "if you don't like it, grow a thicker skin because freedom of speech blah blah blah". Well, no. Even /r/scifi has a "be nice" rule to prevent people from indiscriminately trolling each other. Somehow the sci-fi writing subreddits (especially DestructiveReaders) completely miss the fact that you create the expectations that your members live up (or down) to; saying "free speech" is nothing more than a cop-out for lazy moderators and trolls on a power trip.

I've already created an alternative writing critique subreddit, but given the other sci-fi writing subreddits, I'm not sure if there are enough (at least semi-skilled) writers and readers on Reddit for it to be worthwhile. I'd rather spend more time writing -- and editing my own stories for self-publishing -- rather than deal with pedantic nonsense from clueless fan fiction-level "writers" who have no idea what they're doing, but talk trash like they know everything.

So here's the question: If you write science fiction, do you ask for critiques on Reddit? If not, do you want to create a better place for writers to discuss their original new stories?

And if you do want to create that place, what concrete steps would you take in order to ensure a base level of writing skills, plus a community whose members don't fit the "frustrated egotistical wannabe writer" stereotype?
