There are many reasons why this could be happening, it could be the time of posting, many of your followers could either be sleeping or working, with the feed and so many people posting depends when people look at it and what they see.
This issue has been discussed many times, but no one has come up with a solution just yet.
I literally post from midnight to midnight LOL
I just wanted to get it out there to let it go of my frustration! LOL Cause I know that is happening because a lot of the people that follow me just want the follow back and really dont care for my content.
I also know that I have People that I talk with that like what I do but the same way I am busy and miss a lot of their stuff they miss mine. But not the community it is becoming a joke when it comes to engagement grrrr... but thank You for taking the time to leave your thoughts about it. It really means a lot.
