If I have set this up correctly, with a new profile at WordPress, the No Tall Poppies blog is entirely managed by me, with regards to posting to Twitter, Facebook and LinkedIn. I have selected No Tall Poppies to be the most usual source of posts, rather than Stories My Nana Tells.
The theme Twenty Ten at WordPress lets me choose the level of publication, with each post.
Each post now has a Facebook share button (Like me!), a Tweet button, email option and using the #in tag when I post to Twitter should carry the post through to LinkedIn. Full integration. Full control. Lovely!
