Subreddits are not communities like forums were, on forums you'd get your regular cohort of people alongside newcomers and you'd start to recognise names, in jokes etc.

I don't think Reddit has that same vibe, I barely 'know' anyone on the subreddits I frequent as the nature of it is transitory, at least for the topics I'm interested in, people will stop by to ask a question and leave or lurk.

That's not to say I don't enjoy using Reddit, it's just not the same as forums.
