haha :) It´s not always given that my posts get seen, what also depends on the time I´m posting.
I´m happy about any sort of engagement, if it is upvotes or comments. I don't mind if someone comments on my post but don't upvote, as long as the comment does not read "beautiful photography" or something like this.
The comments help a lot don't they? I have found that those who stick around the longest are those who comment and engage with the comments they receive.
I agree on that point. Very important for me to answer every comment.
some only see the comments as engagement but the upvotes are also - much like a read receipt - with autos being "I read you once upon a time and might again" :D
