It's actually good in my point of view - it will make more people reply to your posts after reading them carefully and putting the time to think and phrase a quality comment - now that they know you will invest your steem power and attention in the quality commenters of your blog.
I will personaly, be more motivated to do as mentioned - I like commenting posts I enjoyed but time is limited and the incentive of your attention and potential upvote makes it much more alluring to invest the limited time on your posts :)
