Subject matter-focused subreddits are actual goldmines (groan) of valuable information. There's one in particular that has built up a collection of actionable advice and data I do not think exists anywhere else, and was the reason I found Reddit to begin with. I'm actually concerned there is no archive outside of Reddit for that info, which means a lot would be lost were the sub to be deleted at some mod's whim one day. That said, I got pulled into Reddit's "suggestions" eventually, and now it is mostly a place for me to view bewb pics, judge and comment on peoples' looks, and just let loose my rampant, unrestrained, anonymous id with impunity.
