Thank you for your explanation, thoughts, and suggestion. Can you please share when you anticipate a fix becoming available for me to implement? If you need anything else from me to assist you please let me know.
Meanwhile I found a configurable section (Settings->Social Integrations) to disable appending opengraph info in headers and another to disable loading Facebook scripts (presume that's not connected to the problem). Based on your suggestions my feedback follows:
1) Don't add any tags at the beginning of your article, add them at the end. That way, they won't be used for description tags.
I had added the tags at the end of the EasyBlog entry but they apparently were still used for description tags because the problem remained.
2) Try to disable the Open Graph abilities of EasyBlog. It may prevent them from pulling the wrong tags and putting them up there.
I disabled appending opengraph info in headers (and loading Facebook scripts) but this didn't fix the problem for me. I've attached an image of the relevant admin screen section.
