Or at least make it out O_O
I'm sure there are people at least unconsciously considering the second last paragraph every time they hit the publish button XD
What I hope for depends entirely on the post. If it's art or hs misc, I hope someone finds it worth a comment (the upvotes are great too) and I'm happy with whatever feedback I get. If it's a progblog they're purely informational so I don't even hope for anything (even several years later I still assume I'm posting into a void) and the comments and upvotes are constantly a pleasant surprise XD
I think some people are posting into a void and think that what they are posting is being seen by many. I reckon this might also be a trap of large upvotes on a newbie post who doesn't yet know the platform well. It makes it appear that they got engagement, when it might not have had much at all - but, they will learn in time.
