That's a really good idea that I hadn't thought about. Thanks! I think I had the idea that I didn't want to write about "current events" because I didn't want to get involved in political discussions...but certainly things like the Bitcoin mini-crash count as current events as well. I'll keep that in mind.
Also, really good point about replying to high quality posts. I tend to think of curation only as upvoting, since that's the curation model on sites I'm used to like Twitter or Instagram.
Where do you tend to find high quality posts? In the trending/hot lists? Or are there better places to look?
