reddit (and the general state of the scene)

[Ofnuts]

I'm active on both reddit (r/Gimp, and some totally SFW r/*porn subreddits ) and several StackExchange sites (StackOverflow, GraphicDesign, SuperUser...).

• Both have the big advantage to support Markdown and have simpler image upload, but they won't allow plain files.
  
• Being "a-social" is an explicit goal of the StackExchange network but the Q&A format is IMHO difficult for beginners. They expect good questions, but beginners barely know what their problem is, so how cannot they ask a "good" question, in the SE meaning of the term. And if you need to ask form more information (often...) the "comments" section show its limits very fast. Answers are voted, so someone who looks up the site has an idea of what the good answers are. But I have seen the real good answers receive less votes than the incorrect/incomplete ones.
  
• Reddit is reasonably nice and usable, but it's really throw-away discussion, you can't have semi-permanent threads.
