Well Lions, while I haven't started to build my subscriber library yet, there's a perk given to my subscribers outright. Anyone who subscribes to me can get any original image I share watermark free to use as a blog thumbnail. In the future my public blogs will be more technical, but my private ones will more personal. More to come! #freecompliments 
Be sure to do some sub only threads so you add to the feed.
Certainly, thank you for the advice. I definitely need to start creating private content. I will be threading images and tidbits not found in my blogs, so I do have a plan. It's still unfolding though, which is to be expected
Very good. That helps. I need more stuff on my private feed.
