Yes, thank you @schamangerbert, i was wondering as well, why the authors selected do not comment more often. They do reply (less than 50%...)to the comment i leave on their post to inform about their selection. But overall some of these authors are really happy to be highlighted, explaining that it means a lot to them, so i guess it's worth, furthermore i decided to share 50% of my post with them to give them a bonus. But i have noticed that somehow the notification when you get replies does not work all the time, so it might be the reason why these authors keep silent as i search for post older than 12-15 hours usually.
