I believe the @joshuaetim post was original, but for a post that makes a bunch of factual claims like this it would have been nice to have some sources and actual numbers to back up the points. As far as @curie goes, any post that makes factual claims like this would typically be expected to provide sources, and some factual data would have made this post a lot stronger in my opinion. If you are interested in @curie curation, look for the TRULY exceptional posts, with professional quality photography, or exquisite writing - and then of course make sure to Google the post a bit to make sure it is original! A good tip is to reverse image search the images as well.

Cheers and good luck - Carl
