Well, aside from the fact they’re not tags, everybody wants to own a subreddit. So right when they got announced, one of the first was ‘Apple’ and I, a macfag, joined immediately. But now there’s ‘mac’ and ‘osx’ subreddits. There’s also a ‘video’ to the earlier ‘videos’ (I joined videos when it appeared, video did not exist, it does not), and a ‘webcomics’ to the earlier ‘comics’ (which specifically covers both in it’s name field). There’s even an xkcd, because a comic that updates three times a week needs to compete with comics/webcomics.
There’s even a ‘meta’ reddit (which probably covers the earlier “ask reddit” but the overlay is not so simple), and a ‘bestof’ (which I’m ok with) and ‘worstof’ reddit.
One of the most heinous crimes against reddit, in my opinion, is the ‘xxx’ subreddit. You know, for porn. Which is what nsfw has always been for, long before users made their own.
Dear redditors: There’s maybe 50 or 60 subreddits, is it really that god damned hard to look for the one you’re making before you make it?
(Edit: Someone suggested this, I wouldn’t leave reddit for it… yet)
