@dave-mackay There is definitely no problem in posting your blogs on your own Facebook page (I have one for my business Access Profiles, Inc.). For the groups on LinkedIn, I do attach my blog through a link to my blog page, but tend to alter my Topic sentences to fit the group.
I also have a local “online” paper that posts my blog articles (North Hills Patch). The administrator of that page told me to “cut and paste” my original blog article and submit it that way.
I guess then my answer to your question would be that (at least in my circumstances) there is no problem in duplicating. The copy is my original work.
Hope others will weigh in with this if there are instances where it is not acceptable.
