The uses that come to mind are the convenience of posting from a multi-network client (e.g. TweetDeck), cross-posting from other networks and for those "RSS/new blog post to network" type scripts. In my opinion, the latter two are the robotic posts that can bog down G+ and the third isn't too far from that.
