Vaguely related: I noticed that the old reddit UI would display self posts as "self.subredditname" and link posts to foo.com as "foo.com". I realized there was a potential confusion if your tld is the subreddit name, and the 2nd and only other label is "self". So I registered self.finance and posted a link to it to /r/finance .
