Excellent piece! Though not upvoting right away will potentially hold back the person's post from going viral.
I can't help but find the timing of upvotes odd. I mean I
the most money I've made from curating (and I've made a lot curating) was from posting within the first 5 minutes and making a ton off of comments and then getting a good $20 later on. I've never made much for voting after 30 minutes.
Not that I'm doubting you. I know a ton of people have posted the same as you regarding the 30 minute mark but it seems it's worked differently for me for some reason.
