What information on reddit is useful?
I used to often see niche, really interesting stuff on there, although I haven't used it much lately. The Frontpage is pure garbage though.
The thing I imagine that gives some people such a negative view is coming in contact through the brand "reddit" and being dumped into large controversial sub-reddits straight away.
A lot of people bump into a particular sub-reddit through a search result and have no idea of the dumpster fires elsewhere on the larger "reddit" site.
Ive had some ok experiences on reddit too, meet ups, bought stuff, got free concert tickets once too. its hard to write the whole thing off. That might be a different era of reddit though. Its been a few years since I had something like that happen now that i think about it
Pick a programming language or piece of popular tech, chances are good it has a subReddit of discussions and links to blog posts and announcements, sometimes with some of the creator/maintainer people posting.
