Do you check who has commented on your post?
One strategy is to interact with the users who are just online and are busy posting and commenting.
I do check older my posts and I respond to all the users who commented my posts.
But I strictly follow a rule that is to comment a post that deserves it. I just respond to a post which has some quality content and I do ignore posts with low standard material.
I do not like to comment every post as I select some posts before commenting.
So, this is my policy and what about yours?
