I think the reason for this is because I first joined about 2 weeks ago and noticed that SP stops you from being able to comment if you run out of resource credit. I was disappointed but at the same time I get it. It's an incentive to have more SP. I exchanged other cryptos I had on binance into STEEM because I see how STEEM is useful to own unlike some of them. But people are for the most part limited on comments they can make unless they invested in SP like I did. I wanted to be able to comment just to have a conversation. Helps that there's actually a change in the payout too since I did that. Completely agree though on the main point. It's a good incentive to follow you. Though I've been commenting on your stuff just cause I'm a big football fan and you write good stuff
