It's great to have every single one of your followers. Not just the 800th one, nor the one which leaves the best comment.
First of all, let me congratulate you, having 800 followers means your content is interesting to many people and that is just enough to give you thanks for, but usually, when we are happy and want to celebrate certain amount of followers, friends, tweets or whatever, we tend to jusr remember the last one or the last ones. To reach 800 you need every single one of the previous 799, and it does not matter if they leave you a comment here today or not. Every single one is important and needed to reach that goal. So for me, leaving a comment today is just not needed. Of course, getting 10 steem is nice but to me, just getting to see your content every time you post, is just a great gift.
Just keep posting, and thank you!
