I would love to use the "publicize" functionality to announce new posts. However, I'm confused by the behavior of the Facebook & LinkedIn vs the Twitter publicity - namely, with both Facebook & LinkedIn, when I update a post, each feed gets a new entry for each update, essentially doing double-entry for those updated posts. Twitter only shows a single entry for the feed.
I want to update/edit my posts after publication without spamming my feed - how can I do that without managing the publicity manually?
The blog I need help with is pteradigm.com.
