Occasionally, HN'ers post some really interesting Wikipedia articles that I didn't know existed, and are fascinating reads, so I personally like them. For example, that was how I learned about Pando[1], thought to be the heaviest known organism, and one of the oldest.
Remember, according to the guidelines, on-topic is,
> Anything that good hackers would find interesting.
Some of us fine obscure Wikipedia articles interesting.
