I know this isn't the first time this has been brought up, I've seen this discussed several times but I couldn't find it using a search. For a community of this size, it doesn't make sense to have posts spread out so thinly across so many different subs.
I guess this is more of an appeal to users than to admins, because I'm not in favor of restricting the creation and use of subs.
For example, it doesn't make sense to post in a separate sub for each country when it could go into /s/worldnews, similarly there are a multitude of conspiracy subs where it would be much simpler to post in /s/conspiracy. Many of these subs have only one page of posts, with the last post being months ago. Having so many redundant subs makes it more difficult to browse a certain topic.
