Blogger owners have the option of Blogger automatically sending new posts to their Google+ profile.
This only works for posts created and posted with Blogger’s editor.
Any post sent to Blogger by TextNut as a draft and later published via Blogger’s own editor will not appear on the owner’s Google+ account. Any post published by TextNut will not appear on the owner’s Google+ account.
I have also tried MacJournal, MarsEdit, Blogo and drafts and posts from these applications are also blocked from using this feature.
