Reddit is an interesting case but at least to me it felt genuine in the early years. Even today I generally trust Reddit comments, but it's important to check the context and commentor before proceeding.
I feel like even though Reddit has undergone various management changes, technology changes, site UI/UX changes -- the core demographic is still there and I hope they don't fuck that up. Once old.reddit.com is gone I'll know the shark has truly jumped. Or maybe someone intelligent will get reigns and understand that domain is not to be fucked with.
