Should be no difference. It looks like different languages. There's de.reddit.com for German, in.reddit.com for Indonesian. SH is Saint Helena I guess, which is a British overseas territory, and thus English. Not sure but that's my guess.
Would be fun and cool if submitter was linking to the Saint Helena version. I wonder what the odds would be, HN submitter + one person of ~4000 people living there, out of almost 8 billion
