Although it was a long time ago, I still remember what it felt like to be a new blogger and get a big upvote - it's very encouraging and inspired me into a habit of consistent posting and building a following. I don't want to compare it to gambling, but it's a little like a slot machine, you put in your time and creative effort blogging day after day, accepting undervalued upvotes earning pennies for the work. Knowing (from experience) that at any moment a big upvote could strike with your next "pull", keeps the bloggers pulling!
