I thnk it helps to first understand why things are the way they are. IMO:
4ch: anonymous, no voting, attracts a lot of people with Asperger's. Lots of gems, tons of garbage, so you need a reasonable foundation to get much out of this place.
/r/: registered, voting up and down, attracts a lot of people with ADHD. Lots of self promotion by way of analysis, so you need to wade through oceans of tedious fluff to get to the core.>>12141540>Reddit is scfuslyl better for information.
My experience is different. I edit the /cyb/ FAQ, much has been compiled from the /cyb/ generals over the last 3+ years (not sure when I started). I did check with Reddit but the discussions were spread out over many different sub reddits and most was just people posting images from elsewhere, possibly to gain status. I got nothing out of my efforts there.
