So after more testing, seems the plugin for WordPress to auto-publish to Instagram isn’t functional, at least for me. Perhaps Instagram doesn’t like the connection, or I have some site conflict with the plugin, but after several attempts, I was unable to configure it to work.
As such, the two streams will continue to co-exist, but as independent entities. Admittedly, I am still challenged to find a role for Instagram, which doesn’t duplicate the role of WordPress, but I am willing to give it a try. Perhaps with some regular use, I can understand the tool a bit better. Or perhaps I am just an older generation that wants more than 5 second social postings.
Regardless, my Instagram entity will remain for the time being, no doubt populated with more random bite size bits of goodness.
