Have you guys ever discussed doing a curation post by scientific topic? The one that springs to mind would be just STEM, of course- a Science post, a Technology post, etc. Alternatively, since Steemstem seems so heavily dominated by science posts over the other three, you could do it with the different sciences- physics, chemistry, biology, etc. (I had this idea a while ago, but it felt self-serving proposing it when I was one of the only people blogging about geology- but there are several other excellent geology bloggers on here now.)

I think that the current strategy you guys are using- the best post from each day strategy- is better overall, but this might be fun do do as a bonus post every now and then.
