It just occurred to me that your issue might simply be due to time zones. Are most Steemlings in the US? Maybe the majority are asleep when you post and by the time they are up, your posts are buried by newer posts.
I'm in the UK and I normally wouldn't Steem until the evening, on the new tab, so I would miss your stuff.
