I made this comment on the site stuff thread:
I no longer want to post anything because of the buttons. It is unclear if just your comment gets posted (which would probably look odd/out of context). So I'm assuming its the whole thread. Whether I hide the buttons or not is irrelevant. If someone else shares and a comment I have made is there then it gets linked to another social networking site.
I appreciate that MN is in the public domain but I have chosen to come to MN to air an opinion or share a problem, not Facebook or google+ etc.
